504 common mode chokes

23 Amp Toroidal Common Mode Choke (504 Series)

West Coast Magnetics’ 504 series common mode chokes provide excellent noise attenuation in a small package. With a continuous RMS current rating in excess of 20 amps, this common mode choke can actually handle up to 50 amps for a short duration of time. This choke also features high noise attenuation in a compact SMD design and is available in tape and reel at larger quantities. WCM504-1 throughWCM 504-6 provide 3 mm of creepage and clearance for safety agency compliance.
