Product Description

Product Overview

This product line features high-performance shielded inductors designed for demanding applications. With a closed magnetic structure, they offer strong electromagnetic interference (EMI) resistance, ultra-low buzzing, and high-density mounting capabilities. Their compact size belies a high current capacity, reaching up to 60A, while maintaining excellent temperature rise and saturation current characteristics even in high-frequency and high-temperature environments. Constructed with low-loss alloy powder and a robust structure, these inductors ensure low resistance and high precision. They operate across a wide frequency range, extending beyond 5MHz, and are Halogen-free for environmental compliance. Ideal for power supply circuits in a variety of electronic devices.
