WCM504 Series 23 Amp Toroidal Common Mode Choke
WCM504 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. WCM504-01 through WCM504-06 provide 3 mm of creepage and clearance for safety agency compliance.

Notes:
- The RMS current rating on this datasheet will lead to an approximate 40° C temperature rise above ambient. These chokes will handle up to 2.5 times this current for a short duration.
- All materials of construction are rated for 155 degrees C continuous service.
