Manufacturing strength is presented as a capability matrix: R&D, quality, process ownership and sustainable production working together.
We have core R&D teams from leading domestic and foreign companies such as Yageo Electronics, Dayi Electronics, Huade Electronics, AEM, Littelfuse, etc., and make strategic investments in the research and development of current sensing resistors and circuit protection products to meet the product needs of customers in the next few decades.
We have passed the ATF16949 automotive regulatory system and have REACH and other certificates. Legal and compliant operations mean that PROSEMI is committed to maintaining high standards in the automotive industry for a long time, providing consistent high-quality products and services and commitment to environmental responsibility.
We have not only broken through the bottleneck technologies in many manufacturing processes, but also broken the monopoly of Germany, the United States and Japan in high-end model series (such as high-power alloy CSR products), becoming one of the few companies in the world with three different technology platforms and a diversified product series.
Our compliance with REACH, RoHS, UL, VED and HF standards ensures that PROSEMI products are safe and environmentally friendly, and we work with you to reduce hazardous substances in electronic products worldwide.
Production resources are organized around capacity, equipment and quality control, helping each base support reliable manufacturing and scalable delivery.
