Product Description
Product Overview
These high-performance magnetic shielding inductors are designed for demanding electronic applications. Featuring a closed magnetic circuit, they offer strong electromagnetic interference (EMI) resistance, ultra-low buzzing, and high-density mounting capabilities. Their compact size belies a high current 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 inductors ensure low resistance and high product precision. They operate across a wide frequency range, extending beyond 5MHz, and are manufactured as halogen-free, environmentally friendly products. Ideal for a wide array of applications including PADs, laptops, desktops, servers, audio systems, networking equipment, security devices, mobile phones, and smart home devices.
