Product Overview
These are high-performance power inductors featuring a shielded structure with a closed magnetic circuit, offering strong electromagnetic interference (EMI) resistance, ultra-low buzzing, and high-density mounting capabilities. They are designed for small size and 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 for high precision, these inductors support a wide operating frequency range of up to 5MHz and above, and are RoHS compliant (halogen-free). They are ideal for applications in PADs, laptops, desktops, servers, audio systems, networking, security devices, mobile phones, and smart home devices.
