Product Description
Product Overview
These high-performance inductors feature a shielded structure with a closed magnetic circuit, providing strong electromagnetic interference (EMI) resistance and ultra-low buzzing. Designed for high-density mounting, they offer small size with high current capabilities up to 60A, maintaining excellent temperature rise and saturation current characteristics in high-frequency and high-temperature environments. Constructed with low-loss alloy powder for low resistance and robust structure, these products ensure high precision and are halogen-free and environmentally friendly. They operate across a wide frequency range, extending beyond 5MHz, and are suitable for a variety of applications including PADs, laptops, desktops, servers, audio equipment, networking, security devices, mobile phones, and smart home devices.
