Product Description
Product Overview
This series of inductors features a shielded structure with a closed magnetic circuit, providing strong electromagnetic interference 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, they offer low resistance, robust structure, and high precision. They operate across a wide frequency range, extending beyond 5MHz, and are halogen-free and environmentally friendly.
