WCM508 Series 30 Amp Toroidal Common Mode Choke

WCM508 series common mode chokes are designed specifically for very low-profile applications. With an rMs current rating of up to 30 amps, noise impedance in excess of 1000 ohms, and a height less than 1.4 cm, this common mode choke packs a lot of performance in a small package.
