2 mH SMD common mode choke

WCM503 Series 12 Amp Common Mode Choke

WCM503 series common mode chokes provide excellent noise attenuation in a small surface mount design. Typical common mode noise impedance is 1 kOhm from 300 kHz to 30 MHz. With a continuous RMS current rating of up to 12 amps, this common mode choke can actually handle a peak current of 30 amps for a short duration of time. These chokes are available in tape and reel at larger quantities.

Notes:

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