Four capacitor families, forty-plus series.
Radial-Lead Aluminium Electrolytic Capacitors
The volume line: 19 series on the A009 catalogue — general purpose (RD, RE), low impedance and high ripple (LF, LJ, LR), long life (LX up to 15,000 h, RV up to 20,000 h at 105°C), high voltage (RF, RG, RR at 160–550 Vdc), high temperature (RJ to 125°C, LH to 130°C), non-polar (NP), low leakage (LL) and the HD family for quick-charge adapters. Range across the group: 6.3–550 Vdc, 0.1–22,000 µF.
Conductive-Polymer Aluminium Solid Capacitors
Six DIP series (PE, PD, PC, PH, PT, PS) and three SMD series (VE, VH, VT), 2.5–100 Vdc, 10–4,700 µF. PH and PS carry 5,000 and 10,000–15,000 h endurance; PT is the 125°C automotive-oriented series and is the one carrying AEC-Q200 on the catalogue — the same series family as the conformity certificates sighted by ChinaMakersHub.
Conductive-Polymer Hybrid Capacitors
HT (DIP) and YT (SMD), 16–100 Vdc, 10–1,500 µF, −55 to +125°C at 4,000 h. Hybrid parts sit between wet electrolytic and solid polymer — low ESR with high ripple tolerance and a wet-cathode failure mode. This line appears on the catalogue but not in the company’s English brochure; ask for datasheets directly.
Surface-Mount Aluminium Electrolytic (V-Chip & SMD)
TE / TF / TG / TR at 6.3–450 Vdc up to 10,000 µF, with TR rated to 130°C; plus the V-chip family RVS, RVT, RVE, RVW, RVH, RVZ, RVL at 4–100 Vdc. Endurance runs 2,000 h on the standard grades to 10,000 h on TG. Taping and packing specifications are published in the catalogue.
Application-Specific Grades
Two worth naming because they answer real specification problems: LX, built for outdoor and street lighting at 12,000–15,000 h; and LG, a GBL non-aqueous electrolyte system rated −55°C specifically for cold starting. Both are catalogue series, not custom developments.
Design Service, Not Only Build-to-Print
The IATF 16949 certificate’s scope reads “design and manufacture of electrolytic capacitors” — design is inside the certified scope, which is the distinction between an ODM and a pure contract builder. The company also lists its own electrolyte development among its capabilities and names itself alongside an external supplier in its raw-material table.
What the registry confirms, and what stays open.
IATF 16949 — and the Scope Line Matters
The certificate sighted by ChinaMakersHub is IATF 16949:2016, issued by a third-party registrar, approved 2024-05-31 on a three-year cycle. Two things were checked against the business licence: the certificate holder is this company, and the credit code on the certificate matches the licence digit for digit. The certified scope reads “the design and production of electrolytic capacitors” — design included. The certified address covers Building 1 floors 2–5, Building 3 and Building 4 at the Gaobu site; the licence records Building 4 only, so the certified footprint is the larger of the two.
AEC-Q200 Rev E 2023 — Verified Part by Part
Five conformity-verification certificates issued 2024-04-09 by a third-party reliability laboratory were read. Each names a specific part number and case size, cites AEC-Q200-Rev E, 2023 (the current revision), and records that the part passed all 14 tests in the standard — visual, electrical, high-temperature storage, temperature cycling, biased humidity, high-temperature operating life, physical dimension, terminal strength, solvent resistance, mechanical shock, vibration, resistance to soldering heat, solderability and surge voltage. Certificate and report numbers are printed on the face of each document.
Two Plants, One Group
Gaobu, Dongguan is the head plant; a second plant operates in Liangtian, Suxian, Chenzhou, Hunan under a separate company in which this entity holds the controlling interest. The product catalogue also carries a Hong Kong group name on its cover. A buyer should ask which entity will sign, invoice and declare — three plausible answers exist and the record does not settle it.
Both Manufacturing and Export Clauses Are on the Record
The registered scope reads “research and development, production, processing and sale of electronic components, electrolytic capacitors and chip capacitors” plus “import and export of goods or technology”. An import/export enterprise code is on file and the company is a VAT general taxpayer. Unlike most listings on this platform, the export route is not an open question at the clause level — only the group-entity question above remains.
Headcount: 129 Insured Against 406 Stated
The enterprise record shows 129 social-insurance contributors; the company’s own materials state 267 at Dongguan and 139 at Chenzhou, 406 in total across the two sites. The two plants sit under two different companies and therefore two different insurance registrations, which explains part of the gap. Stated here so a buyer can ask for a headcount in writing per site.
Raw-Material Sourcing Is Published
The catalogue prints a supplier table by material — anode and cathode foil, electrolytic paper, lead wire, aluminium case, rubber, sleeve, electrolyte and terminal cover — naming Japanese foil and paper suppliers among them, and listing the company itself alongside an external chemical supplier for electrolyte. Published bills of material are rare at this size and are worth verifying against incoming-inspection records on an audit.
What was checked — and what the check found.
The registry read is done and it supports the stamp: the business licence was sighted, the 18-digit credit code passes the national check-digit rule with a 441900 prefix matching the registered Dongguan address, and the same code appears digit for digit on the IATF 16949 certificate. The registered scope carries both a manufacturing clause and an import/export clause, an import/export enterprise code is on file, and no abnormal-operation, administrative- penalty, enforcement, dishonesty or serious-violation record was visible on the enterprise snapshots read between 2026-08-26 and 2026-09-09. Two certificates were read as documents rather than taken on trust: IATF 16949:2016 with a certified scope that includes design, and five AEC-Q200 Rev E 2023 conformity verifications on named part numbers. What is stated rather than resolved: 129 insured contributors against 406 headcount claimed across two sites under two companies; a Hong Kong group name on the catalogue cover alongside the two mainland plants, so the signing and invoicing entity should be named before order; a temperature ceiling published as 130°C on the current catalogue against 150°C in the English brochure; four different English renderings of the company name across its own channels; and no MOQ, sampling or production lead time on file at all. What would close it: certificate originals with numbers and expiry, per-site headcount in writing, the group-entity answer, and commercial terms.
A capacitor plant, read off the record and the certificates.
TOPAZCON is the brand of Guangdong Topaz Electronic Technology Co., Ltd. (广东黄宝石电子科技有限公司), an aluminium-electrolytic capacitor maker at Gaobu, Dongguan, with a second plant at Liangtian, Chenzhou, Hunan. The current company was registered on 2014-07-15; the brand and its predecessor operation date to 2001 on the company’s own account. Registration was read against the business licence and enterprise records in September 2026: active, with manufacturing and import/export clauses both in the registered scope.
The technical position is narrow and stated plainly on every piece of the company’s material: high-temperature, long-life electrolytic capacitors. The A009 catalogue runs 182 pages across four families — radial-lead aluminium electrolytic, conductive-polymer solid, polymer hybrid, and surface-mount — totalling more than forty series from 6.3 to 550 Vdc and 0.1 to 22,000 µF, with a published ceiling of 130°C and endurance to 20,000 hours at 105°C on the longest-life series. Two certificates back the quality claim rather than merely naming it: IATF 16949 covering design as well as production, and AEC-Q200 Rev E 2023 conformity verification on named parts.
Read the record as it is: a national high-tech enterprise and a 2025 provincial “specialised and innovative” SME, no adverse record on the snapshots, both plants disclosed, raw-material suppliers published. Open and stated: no MOQ or lead time has been provided; insured headcount is well below the stated total; the group carries a Hong Kong name alongside two mainland companies; and the company’s own channels give four different English names and two different temperature ceilings. Contact routes through ChinaMakersHub; direct details are exchanged after first inquiry.
From 2001 to AEC-Q200, on the record.
Brand and predecessor operation begin
The company dates TOPAZCON and its predecessor electronics operation in Dongguan to 2001. This is the company’s own account; the current legal entity is separately registered in 2014 and both dates are shown here rather than merged.
Current entity registered in Dongguan
Guangdong Topaz Electronic Technology Co., Ltd. is registered on 2014-07-15 with capacitor research, production, processing, sale and goods/technology import-export in scope. Confirmed against the business licence and the enterprise record.
Second plant and provincial recognition
A second plant is established at Chenzhou, Hunan and later brought into production; the company is recognised as a national high-tech enterprise and, in 2025, as a Guangdong provincial specialised-and-innovative SME. Construction and award dates are the company’s own account; the standings appear on the enterprise record.
IATF 16949 and AEC-Q200 verification
IATF 16949:2016 is approved on 2024-05-31 with a certified scope covering the design and production of electrolytic capacitors. Five AEC-Q200-Rev E 2023 conformity-verification certificates are issued on 2024-04-09 against named part numbers, each recording 14 of 14 tests passed. Both were read as documents by ChinaMakersHub.
Listed on ChinaMakersHub
Registry read 2026-09-09 against the licence and enterprise records: active, manufacturing and export clauses both present, no adverse record. Open and stated: commercial terms, per-site headcount, the group entity that signs and invoices, and the two different temperature ceilings published across the company’s own materials.
Where these capacitors go to work.
LED Lighting & Driver Makers
The longest-life series were built for this: LX at 12,000–15,000 h for outdoor and street lighting, LJ and LR for driver boards. Send the driver’s ripple current, ambient and target lifetime — the endurance figure alone does not answer the question.
Automotive Electronics & Tier Suppliers
PT and LR carry AEC-Q200 on the catalogue and the PT family is the one with conformity certificates sighted here. Ask for the certificate covering the exact part number you intend to qualify, not the family — AEC-Q200 is verified part by part.
Power Supply & Charger Brands
HD, HDX, HDM and HDT are the quick-charge adapter grades at 400–500 Vdc; RF, RG, RR and RV cover high-voltage bulk at 160–550 Vdc with 8,000–20,000 h endurance. Specify case height limits early — miniaturisation is where these series differ.
Industrial & EV Charging Equipment
Snap-in and high-voltage grades for inverters, chargers and welding equipment. For 125°C and 130°C requirements the RJ, LH, TR, PT, VT, HT and YT series are the relevant families; ask for ripple-current multipliers at your switching frequency.
Consumer Electronics & Appliance OEMs
Surface-mount TE / TF / TG and the V-chip family suit high-density automated assembly; taping and packing specifications are published in the catalogue. Confirm reel format and MSL handling with the line you will run them on.
Distributors & Catalogue Buyers
More than forty series with published voltage, capacitance, temperature and endurance ranges — a broad enough catalogue to consolidate. The open items are commercial: no MOQ or lead time has been stated, and the invoicing entity should be settled first.

Frequently Asked Questions
What does TOPAZCON make?
Aluminium electrolytic capacitors in four families: radial-lead wet electrolytic, conductive-polymer solid (DIP and SMD), polymer hybrid, and surface-mount including a V-chip range. The A009 catalogue lists more than forty series from 6.3 to 550 Vdc and 0.1 to 22,000 µF, with a published temperature ceiling of 130°C and endurance to 20,000 hours at 105°C on the longest-life series.
Is the AEC-Q200 claim verified?
Five conformity-verification certificates were read as documents. Each was issued on 2024-04-09 by a third-party reliability laboratory, names a specific part number and case size, cites AEC-Q200-Rev E 2023, and records that the part passed all 14 tests in the standard. Certificate and report numbers are printed on each. Note how AEC-Q200 works: it verifies parts, not companies — ask for the certificate covering the exact part number you intend to qualify, and for the current originals with issue and expiry dates.
What does the IATF 16949 certificate actually cover?
The scope line on the certificate reads “the design and production of electrolytic capacitors” — design is inside the certified scope, which matters if you are asking for a part developed to your specification rather than built to your print. The holder name and credit code match the business licence digit for digit. Approved 2024-05-31 on a three-year cycle; ask for the original to confirm the certificate number and expiry date before an audit.
Can it export in its own name?
The registered scope carries an 「货物或技术进出口」 (import/export of goods or technology) clause and an import/export enterprise code is on file, so at the clause level the answer is yes. One question remains open: the product catalogue carries a Hong Kong group name on its cover alongside the two mainland companies, so ask which entity will sign the contract, issue the invoice and appear on the customs declaration — and confirm they are the same one.
How big is the operation?
Two plants: the head plant at Gaobu, Dongguan and a second at Liangtian, Chenzhou, Hunan operated by a controlled affiliate. The company states 267 staff at Dongguan and 139 at Chenzhou, 406 in total; the enterprise record for this entity shows 129 social-insurance contributors. The two sites sit under two companies with separate insurance registrations, which explains part of the gap. Ask for a headcount in writing per site and a walkthrough of both.
What are the MOQ and lead times?
None have been provided. No MOQ, sampling time or production lead time appears anywhere in the material on file, so this listing states none rather than guessing. Send your part number, annual volume and required lifetime through ChinaMakersHub and ask for terms in writing with units.
What did the ChinaMakersHub check find?
Run on 2026-09-09 against the business licence and Chinese enterprise-data snapshots dated 2026-08-26 to 2026-09-03: the company is active (存续), registered 2014-07-15 in Gaobu, Dongguan; the 18-digit credit code passes the national check-digit rule with a 441900 prefix matching the address and is identical on the licence, the enterprise record and the IATF certificate; the scope carries both manufacturing and import/export clauses; an import/export enterprise code is on file; the company is a national high-tech enterprise and a 2025 Guangdong specialised-and-innovative SME; no abnormal-operation, administrative-penalty, enforcement, dishonesty or serious-violation record was visible. Registered capital was reduced in January 2026 and a new licence issued the same day — a recorded corporate action, noted here as a fact rather than a finding.
Why does the page mention two different temperature ceilings?
Because the company’s own materials give two. The English brochure states a range to 150°C; the A009 product catalogue — the more specific and more recent document — publishes a ceiling of 130°C on the TR and LH series. This page uses the catalogue figure and states the discrepancy rather than choosing the larger number. If you need parts above 130°C, ask for the specific series and its datasheet before designing them in.
Talk to TOPAZCON Capacitors directly.
Send the part number or the electrical requirement — capacitance, voltage, ripple current, ambient temperature and target lifetime — and ask for the datasheet plus the AEC-Q200 certificate covering that exact part. Ask for MOQ and lead times in writing with units, and for the entity that will sign and invoice. ChinaMakersHub will route the request.
