What 上海美星电子有限公司 does

Shanghai Meixing Electronics Co., Ltd. (上海美星电子有限公司) is a privately held Chinese manufacturer of electronic transformers and inductors, founded in May 1998 and headquartered in Shanghai's Xuhui District. The company designs, manufactures, and assembles magnetic components across six core product series — EE, ED, EF, PK, MX, and RING CORE — used in switching power supplies, ballasts, line filters, and pulse transformer applications. Reported annual production capacity is approximately 150 million units, supported by a factory in Shanghai's Songjiang District and a production base in Shuyang County, Jiangsu Province. The company holds ISO9001, ISO14000, UL, and TS16949 (IATF 16949 equivalent) certifications, the latter enabling automotive supplier qualification.

The company's primary customer segment is the global green lighting industry, where its magnetic components are embedded in Philips Lighting products shipped across North America, Europe, India, and other regions, with additional tier-1 customers including GE, Japan Fujitsu Group/FDK, and COSEL. In recent years the company has expanded into new energy vehicle motor control systems (with adoption by BAIC and Changan Automobile) and industrial power supply products (recognized by COSEL). Revenue is generated through hardware sales via direct enterprise field sales relationships and a company-operated online shopping mall portal, with quote-based pricing and downloadable product datasheets; no public pricing is disclosed. The company is privately held with no disclosed parent, no public listing, no funding rounds recorded, and no management team information in the source data.
