SNCMC Nanocrystalline Common Mode Chokes

Signal Transformer / Bel SNCMC Nanocrystalline Common Mode Chokes provide high efficiency and low power loss in a small, lightweight package designed for vertical mounting. The superior material properties of the nanocrystalline core enable common mode chokes with high inductance / impedance with a small number of turns. This design results in low winding capacitance, reduced copper losses, and excellent attenuation performance. The SNCMC series offers 1.5KV minimum dielectric strength, -25°C to +130°C operating temperature range, and RoHS and REACH compliance. Signal Transformer / Bel SNCMC Nanocrystalline Common Mode Chokes are suited for high-current applications, commercial and consumer electronics, electrical networks, and electronic equipment.
