Product Description
Product Overview
This product is a series of shielded power inductors designed for high-density mounting and excellent electromagnetic interference (EMI) suppression. Featuring a closed magnetic circuit, they offer ultra-low buzzing and are ideal for applications requiring 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 a robust structure, they ensure high product precision and low resistance. They operate across a wide frequency range, extending above 5MHz, and are halogen-free for environmental compliance. Applications include PADs, laptops, desktops, servers, audio systems, networking equipment, security devices, mobile phones, and smart home devices.
Product Attributes
- Material: Alloy powder
- Environmental Compliance: Halogen-free
