Product Overview
This product line features high-performance shielded inductors designed for demanding applications. They offer excellent electromagnetic interference (EMI) suppression, ultra-low audible noise, and high-density mounting capabilities due to their closed magnetic circuit structure. Engineered with small form factors and high current handling up to 60A, these inductors maintain superior temperature rise and saturation current characteristics even in high-frequency and high-temperature environments. Constructed with low-loss alloy powder and robust build, they ensure high product accuracy and low resistance. With a wide operating frequency range extending beyond 5MHz and halogen-free environmental compliance, these inductors are ideal for a variety of electronic devices including PADs, laptops, desktops, servers, audio systems, networking equipment, security devices, mobile phones, and smart home appliances.
