Product Overview
This product is a series of shielded power inductors designed for high-density mounting and robust performance in demanding environments. Featuring a closed magnetic circuit, they offer strong electromagnetic interference (EMI) resistance and ultra-low audible noise. Their compact size belies a high current capability, reaching up to 60A, with excellent temperature rise and saturation current characteristics, even at high frequencies and temperatures. Constructed with low-loss alloy powder and a durable structure, these inductors ensure high precision and low resistance. They operate across a wide frequency range, extending beyond 5MHz, and are RoHS compliant (halogen-free). Applications include PADs, laptops, desktops, servers, audio systems, networking equipment, security devices, mobile phones, and smart home devices.
Product Attributes
- Material: Low-loss alloy powder
- Compliance: Halogen-free (RoHS compliant)
