Product Overview
This series of inductors features a shielded structure with a closed magnetic circuit, providing strong electromagnetic interference (EMI) resistance, ultra-low buzzing, and high-density mounting capabilities. Designed for compact size and high current handling up to 60A, these inductors maintain excellent temperature rise and saturation current characteristics in high-frequency and high-temperature environments. They are constructed with low-loss alloy powder die-casting for low resistance, structural robustness, and high product precision. With a wide operating frequency range extending beyond 5MHz, these products are also halogen-free and environmentally friendly. They are ideal for applications in PADs, laptops, desktops, servers, audio systems, networking equipment, security devices, mobile phones, and smart home devices.
