 selling film capacitor. 

Founded in May 2002, Shenzhen Shenfeng Electronics Co., Ltd. is a specialized enterprise dedicated to the R&D, production, sales, and technical services of high-end film capacitors. The company has obtained IATF16949 Automotive Quality Management System certification and has been recognized as a National High-Tech Enterprise, Shenzhen High-Tech Enterprise, and Shenzhen Specialized, Refined, Unique, and Innovative Enterprise. Currently offering 33 product series with over 2,000 specifications, the company's double-sided metallized tandem-structure capacitors have established a dominant position in the industry. It provides one-stop services to meet customer needs.

 

The company's products and production processes have won numerous national invention patents and utility model patents. The X2 class electromagnetic interference-resistant capacitors have obtained five globally authoritative quality certifications, namely: China's CQC certification, the UK's CB certification, Germany's VDE certification, the US and Canada's UL certification, and South Korea's KC certification. The company maintains mature design specifications for core metallized films and a synchronized supply chain system. From adhesive particles and base films to evaporation manufacturers, it implements strict targeted procurement of film materials. This includes automotive-grade and industrial-grade materials, specialized low-noise materials, dual 85 materials, and some standard military-grade materials. The IQC incoming material inspection process now incorporates metallographic microscopy sampling for each batch of metallized films, rigorously preventing defects such as oxidation, coating scratches, and edge irregularities. Additionally, the company has established a multifunctional reliability laboratory that conducts pulse testing, charge-discharge testing, flame retardancy testing, dual 85/95 testing, low-noise testing, tensile testing, high/low-temperature shock testing, and durability testing, ensuring 100% compliance for every finished product batch.

 

The company is equipped with state-of-the-art automated production and testing systems, featuring four optimized manufacturing processes: automotive-grade, industrial-grade, dual 85, and low-noise technologies. Its products serve diverse applications including industrial automation, industrial frequency converters and servo systems, EV onboard chargers and charging stations, high-power welding equipment with industrial inverter welding power supplies, photovoltaic inverters and energy storage solutions, rail transit power systems, UPS solutions, as well as smart home appliances like computer switch-mode power supplies.
