Product Description
Product Overview
This series of inductors features a shielded structure with a closed magnetic circuit, offering strong electromagnetic interference (EMI) resistance, ultra-low buzzing, and high-density mounting capabilities. Designed for compact size and high current handling up to 60A, they maintain excellent temperature rise and saturation current characteristics in high-frequency and high-temperature environments. Constructed with low-loss alloy powder, these inductors exhibit low resistance, robust structure, and high product precision. They operate across a wide frequency range, extending beyond 5MHz, and are halogen-free and environmentally friendly. Applications include PADs, laptops, desktops, servers, speakers, networking equipment, security systems, mobile phones, and smart home devices.
Product Attributes
- Material: Low-loss alloy powder
- Environmental: Halogen-free
