Shanghai Yongming Electronic Co., Ltd.

Shanghai Yongming Electronic Co., Ltd., which markets its products under the YMIN brand, is a Chinese capacitor manufacturing enterprise that integrates design, research and development, production, sales and service. The company was established in 2004 and is headquartered in Fengxian District, Shanghai, where it occupies a site of approximately 33,400 square meters. Over nearly two decades it has built up independent R&D and manufacturing know-how, a technical management team and a mature capacitor production process. YMIN's core business is capacitors. Its main product family is diversified aluminum electrolytic capacitors, offered in radial-leaded, SMD, snap-in and screw-terminal types. Around this core the company has extended into conductive polymer aluminum solid electrolytic capacitors, conductive polymer hybrid aluminum electrolytic capacitors, multilayer polymer aluminum solid electrolytic capacitors (MLPC), multilayer ceramic capacitors (MLCC), conductive tantalum capacitors, metallized polypropylene film capacitors, and electric double-layer capacitors (EDLC) and hybrid supercapacitors. The company states an annual output of 2 billion capacitors. Positioning is built on high-performance and customized capacitor solutions. YMIN says it cooperates closely with counterparts in Japan and South Korea on technology, giving it strength in capacitors that endure high temperature, high voltage, high ripple current and high frequency. Its products are used in automotive electronics, PD quick chargers, LED smart lighting, 5G and IoT devices, and increasingly in AI data servers, robotics, drones, energy storage and power supplies. The company emphasizes a customized capacitor service that it presents as a differentiator and that has earned it a reputation internationally. YMIN exports to Europe, the Americas, Southeast Asia and other regions, and maintains an active marketing and trade-show presence, including events such as PCIM Asia and the China International Computing Expo, where it has promoted capacitor solutions for AI data centers and 800V EV drive platforms. The company is privately held and is not known to be listed on a stock exchange.

Shanghai Yongming Electronic Co., Ltd. was established in 2004 as a capacitor manufacturing enterprise. From its base in Fengxian District, Shanghai, the company set out to combine design, research and development, production, sales and service under one roof. Over almost twenty years it accumulated independent R&D and production experience, built a technical management team and developed a mature capacitor manufacturing process. The company's early and continuing core has been aluminum electrolytic capacitors, which it produces in radial-leaded, SMD, snap-in and screw-terminal formats. As electronics demand shifted toward higher reliability, higher frequency and smaller form factors, YMIN broadened its portfolio into conductive polymer aluminum solid electrolytic capacitors, conductive polymer hybrid aluminum electrolytic capacitors, multilayer polymer aluminum solid electrolytic capacitors (MLPC), multilayer ceramic capacitors (MLCC), conductive tantalum capacitors, metallized polypropylene film capacitors, and electric double-layer capacitors (EDLC) and hybrid supercapacitors. YMIN has emphasized technology cooperation with counterparts in Japan and South Korea, which it credits for advancing the performance of its capacitors in enduring high temperature, high voltage, high ripple current and high frequency. This capability supported expansion into demanding applications such as automotive electronics, PD quick chargers, LED smart lighting, 5G and IoT devices. The company reports an annual output of 2 billion capacitors and exports to Europe, the Americas, Southeast Asia and other regions. In recent years YMIN has aligned its product development and marketing with newer growth markets. It has promoted capacitor solutions for AI data servers, robotics, drones, energy storage and power supplies, and has exhibited at industry events including PCIM Asia and the China International Computing Expo. Its MDP series film capacitors and solid-liquid hybrid capacitors have been positioned for 800V EV drive platform DC-Link and drone brushless ESC applications respectively. The company remains privately held and operates as a specialized capacitor manufacturer rather than a diversified conglomerate.
