The magnetic core of this product is made of high-quality nickel core magnetic materials from Taiwan and Japan. The magnetic core can withstand high current, low temperature coefficient and stable characteristics. The enamelled copper wire can withstand the 180℃high-temperature wire to ensure the quality of the product.
The production process adopts full automation, fast production speed and fast delivery time are our first advantages. Our high-quality CD31-105 chip inductor solves the problem of insufficient current power and space for customers, which is deeply loved by customers in China, Europe and America.
