1. Product Introduction of STDR Chip Inductor
STDR chip inductor: The core is made of high quality nickel core magnet from Taiwan and Japan. The core can withstand high current, low temperature coefficient and stable performance. Enameled copper wire is made from Pacific 180℃high temperature line, which can effectively ensure the quality of the product.
Fully automated production process, fast production speed, fast delivery is our first advantage. Our high quality Tablet Series inductors are popular in China, Europe and America to solve the problems of high current power and insufficient space.
