WCM501 Series SMD Common Mode Choke
WCM501 series common mode chokes are designed to attenuate common mode line noise in switching power supplies. These chokes provide a typical minumum 15 dB of attenuation from 100 kHz to 30 MHz. They are offered in two package styles. A low profile surface mount package is compatible with pick and place equipment. A larger through-hole package offers greater attenuation and is also compatible with pick and place equipment.
