CENKER CKST1205-2.2uH M B compact shielded inductor with strong EMI resistance and low buzzing noise
Product Overview
This product line features high-performance shielded inductors designed for demanding applications. With a closed magnetic circuit structure, they offer strong electromagnetic interference (EMI) resistance, ultra-low buzzing, and high-density mounting capabilities. These compact inductors deliver high current ratings up to 60A while maintaining excellent temperature rise and saturation characteristics in high-frequency and high-temperature environments. Constructed with low-loss alloy powder and a robust, precision-engineered design, they ensure low resistance and structural integrity. They operate across a wide frequency range, extending beyond 5MHz, and are RoHS compliant (halogen-free and environmentally friendly).
