Product Overview
These high-performance power inductors are designed for demanding applications, offering excellent electromagnetic interference (EMI) shielding, ultra-low buzzing, and high-density mounting capabilities. They feature a compact size with high current handling up to 60A, maintaining superior temperature rise and saturation current characteristics even 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 RoHS compliant (halogen-free). Ideal for power supply circuits in a wide array of electronic devices including PADs, laptops, desktops, servers, audio systems, networking equipment, security devices, mobile phones, and smart home appliances.
