CMF Common Mode Frame Chokes

Triad Magnetics CMF Series Common Mode Frame Chokes provide exceptional common-mode suppression and stray inductance to suppress differential mode noise. The CMF Series combines the features of two separate components into one. The chokes are compact and are available in either vertical configuration (uses minimal board area) or horizontal configuration (low profile applications). Triad Magnetics CMF chokes feature a 250VAC rated voltage, a 0.45A to 2.3A rated current range, and a 10mH to 100mH inductance range. The Triad Magnetics CMF Series have an operating temperature of -40°C to +105°C and creepage and clearance of >3mm. The components are frequently used in LED lighting, electronics ballast, and switch-mode power supplies.
