What PolyCap does
PolyCap (柏瑞凯电子科技股份有限公司) is a privately held Chinese high-tech manufacturer of conductive polymer solid aluminum electrolytic capacitors, founded in 2011 in Shenzhen by Dr. Wang Binhua (汪斌华博士). The company specializes in R&D, production, and sale of solid aluminum capacitors using proprietary PEDOT (poly(3,4-ethylenedioxythiophene)) conductive polymer electrolyte technology across three form factors — radial lead (DIP), surface mount (SMD), and stacked multi-layer chip (MLPC) — plus solid-liquid hybrid variants. Its technology platform is rated 'international leading level' by the China Electronic Components Association (October 2021) and delivers ultra-low ESR (as low as 5mΩ), operation up to 165°C, lifespans up to 23,000 hours, and AEC-Q200 automotive-grade certification across multiple product series. The company has been designated a National High-Tech Enterprise and a third-batch National 'Specialized and Innovative Little Giant' enterprise.
The company operates a 59,000 sqm manufacturing facility at the Ganzhou Industrial Park in Jiangxi Province with current production capacity of 180 million units per month, expandable to 250 million, supplemented by an R&D headquarters in Shenzhen that was significantly expanded with a new dedicated R&D building in January 2023. PolyCap sells directly to enterprise OEMs and contract manufacturers via a sales-led, technical pre-sales motion; products are not distributed through third-party channels. Pricing is quote-based on specifications, volume, and multi-year contract terms. The company's products serve five primary verticals: automotive electronics (CATL, EV charging, control systems), 5G communications and industrial automation (5G base stations, photovoltaic inverters), AI servers and data centers (ByteDance, Alibaba), consumer electronics (Samsung, LG, Xiaomi, OPPO, vivo, Honor), and power supply/lighting (GoodWe, Huntkey). Notable customer logos include Samsung, LG, Lenovo, ZTE, CATL, ByteDance, Alibaba, Xiaomi, OPPO, vivo, Honor, New H3C, Ruijie, GoodWe, Huntkey, and Deye.

PolyCap product offering
Product offeringCore offering
PolyCap manufactures conductive polymer solid aluminum electrolytic capacitors, solid-liquid hybrid aluminum capacitors, and multi-layer chip (MLPC) aluminum capacitors in radial lead (DIP), surface mount (SMD), and stacked form factors. Products use proprietary PEDOT conductive polymer electrolyte technology and serve automotive electronics (AEC-Q200), 5G communications, AI servers/data centers, industrial automation, power supplies, and consumer electronics applications, with operating voltages from 2V to 250V and temperatures up to 165°C.
Product overview
PolyCap (柏瑞凯) is a manufacturer of conductive polymer solid aluminum capacitors and hybrid (solid-liquid mixed) aluminum capacitors. The product portfolio comprises three main form factors: radial lead type (径向引线型/DIP), surface mount type (表面贴装型/SMD), and stacked/multi-layer type (片式叠层型/MLPC). Key product series include: RK (23000h/105℃ ultra-long life radial), VK (23000h/105℃ SMD), VX (150℃/2500h ultra-high temperature SMD), VH (4.5mm low-height SMD for portable devices), and the HZ/HK/HP/HU series hybrid SMD capacitors with AEC-Q200 automotive certification. All products use PEDOT (poly(3,4-ethylenedioxythiophene)) conductive polymer electrolyte technology, achieving extremely low ESR values (as low as 5mΩ), wide voltage ranges (2.5V~250V), and operating temperatures up to 165℃. Products serve automotive (AEC-Q200), 5G base stations, AI servers, industrial automation, power supplies, and consumer electronics.
