Product Description
Product Overview
This product is a series of high-performance inductors designed for demanding applications. They feature a shielded structure with a closed magnetic circuit, offering strong electromagnetic interference (EMI) resistance, ultra-low buzzing, and high-density mounting capabilities. The inductors are characterized by their small size and high current handling capacity, reaching up to 60A, while maintaining excellent temperature rise and saturation current characteristics in high-frequency and high-temperature environments. Constructed with low-loss alloy powder and a robust structure, these components ensure high product accuracy and low resistance. They operate across a wide frequency range, extending beyond 5MHz, and are RoHS compliant (halogen-free and environmentally friendly).
Product Attributes
- Material: Low-loss alloy powder
- Environmental Compliance: Halogen-free
