Product Overview
This product line features high-performance shielded inductors designed for demanding electronic applications. With a closed magnetic circuit structure, they offer strong electromagnetic interference (EMI) resistance, ultra-low buzzing, and high-density mounting capabilities. These inductors provide high current capacity in a compact size, maintaining excellent temperature rise and saturation current characteristics even in high-frequency and high-temperature environments. Constructed with low-loss alloy powder and low resistance, they ensure structural integrity and high precision. They operate across a wide frequency range, extending beyond 5MHz, and are RoHS compliant (lead-free and environmentally friendly).
