25 Amp Toroidal Common Mode Choke

West Coast Magnetics' 502 series common mode chokes are designed to attenuate common mode line noise. These common mode chokes can handle currents up to 25 amps and are available in vertical and horizontal mount packages. They provide a typical minumum15 dB of attenuation from 50 kHz to 30 MHz. They feature interwinding isolation of 1500 Vac and 3mm clearance for safety requirements.
