CMX1211 Series

Wire-Wound SMT Power Common Mode Chokes

Product Description

Increased focus on EMI filtering on high power devices along with concerns over device size have led to Laird's introduction of Wire Wound SMT Power Common Mode chokes providing lower losses and handling higher power capabilities. Their extremely small size and less weight satisfy user demands. They also offer stable performance and high suppression of asymmetric interference at both low and high frequencies.
