Product Overview
This product is a series of shielded inductors designed for high-density installation and robust performance in various electronic applications. Featuring a closed magnetic circuit, these components offer strong electromagnetic interference (EMI) resistance and ultra-low buzzing. They are engineered for high current capabilities, with ranges extending up to 60A, and maintain excellent temperature rise and saturation current characteristics even in high-frequency and high-temperature environments. Constructed with low-loss alloy powder, they offer low resistance and high structural integrity. These products are halogen-free and environmentally friendly, suitable for a wide operating frequency range up to 5MHz and beyond.
Product Attributes
