Yiyang Huawei Electronic Technology Co., Ltd., founded in 2003, is situated in Longling Industrial Park, Heshan District, Yiyang City. Covering a land area of over 1.53 hectares (equivalent to 23 mu), the company employs more than 100 team members, among whom 38 are engaged in R&D, technical and management roles.
In 2011, we rolled out a full quality management system aligned with GB/T 19001 (ISO 9001) and acquired the corresponding official certification.
Our core product portfolio covers a full range of medium & high-voltage aluminum electrolytic capacitors, as well as low-voltage non-polarized series including CD11G, CD288H, CD291~293, CD71 and CDS. After years of technical iteration, our capacitors feature stable, consistent quality and are distributed nationwide. Widely adopted across end applications including switching power supplies, LED drivers, mobile phone chargers, EV chargers, EV charging piles and inverters, our production capacity hits hundreds of millions of units annually.
To capture high-end electronics market demand, we set up an independent R&D division and poured millions of RMB into lifespan and reliability testing & research. Heavy investment in manpower, raw material screening, process optimization and equipment upgrading has greatly lifted overall product performance. Our newly mass-produced CD11GH and CD293 series — high-capacity, high-voltage aluminum electrolytic capacitors with premium performance — enjoy strong market traction and promising market prospects. The enterprise has also been certified as a National High-Tech Enterprise and a Hunan Provincial SRDI (Specialized, Refined, Differential & Innovative) SME.

All our team members will collaborate closely, conduct in-depth technical research and operate with pragmatism, aiming to reach top-tier industry standards within the next few years. We integrate independent R&D, manufacturing and after-sales services, with brand building for "SIQING" as our core corporate philosophy.
