Common Mode Noise Filtering Chokes – CM1309 Series

Bourns CMCs are designed with a high permeability ferrite core for filtering in industrial and commercial applications

Image of Bourns Common Mode Noise Filtering Chokes – CM1309 Series Bourns CM1309 series common mode chokes are designed for filtering common mode noise in a wide range of industrial and commercial applications such as energy storage, enterprise computing, and green energy. They offer a nominal inductance range from 1 mH to 8.7 mH and a current range from 0.7 A to 2.8 A with a footprint measuring 13 mm long, 9.2 mm wide, and 16 mm high. A high permeability ferrite core results in self-resonant frequencies ranging from 390 kHz to 1.6 MHz, which is ideal for filtering high-frequency switching supplies with temperature ratings from -40°C to +125°C.
