CMF Series Dual Mode Chokes

Designed to suppress noise from switch mode power supplies and other sources, the versatile CMF series dual mode chokes from Triad Magnetics feature superior performance, reliability, and economy in an innovative dual function open-frame design that fits easily into a wide variety of devices and systems. The advanced CMF series dual mode chokes feature an economical dual-function design, which effectively combines the features of two separate components into one. They provide both exceptional common-mode noise suppression, and their stray inductance is highly effective in suppressing differential mode noise. In many applications, designers are forced to use two separate components to guard against both types of noise. A choke is necessary for common mode noise suppression and a separate inductor is needed to filter out differential mode noise. This more complicated approach requires installing two components and occupies additional board space, which adds to production costs and can pose reliability issues. The dual-function CMF series chokes solve all those problems. They are ideal for suppressing both types of noise in a wide range of applications including switch mode power supplies, LED lighting, electronics ballast, and other devices. They are compact in size and come in either a horizontal package (where height clearance is a concern) or a vertical package that requires minimal board space.
