Product Overview
This product line features high-performance shielded inductors designed for demanding electronic applications. Key advantages include a shielded magnetic structure that offers strong electromagnetic interference (EMI) resistance, ultra-low buzzing, and high-density mounting capabilities. These inductors offer a compact form factor with high current ratings up to 60A, 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 product precision. They operate across a wide frequency range, extending above 5MHz, and are RoHS compliant (halogen-free and environmentally friendly).
