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, these components maintain excellent temperature rise and saturation current characteristics in high-frequency and high-temperature environments. Constructed with low-loss alloy powder for low resistance and robust structure, they ensure high product accuracy. They operate across a wide frequency range, extending beyond 5MHz, and are RoHS compliant (halogen-free). Suitable for a wide array of applications including PADs, laptops, desktops, servers, audio equipment, networking devices, security systems, mobile phones, and smart home devices.
Product Attributes
- Material: Low-loss alloy powder
- Environmental Compliance: Halogen-free
