Bourns CM1309 Common Mode Chokes offer a nominal inductance range of 1mH to 8.7mH and a 0.7A to 2.8A current range. These chokes are designed to filter common mode noise in a wide range of commercial and industrial applications, including energy storage, enterprise computing, and green energy. The CM1309 chokes have a small footprint of 13mm x 9.2mm x 16mm. Bourns CM1309 Common Mode Chokes feature a high permeability ferrite core that results in self-resonant frequencies ranging from 390kHz to 1.6MHz, suitable for filtering high-frequency switching supplies with temperature ratings from -40°C to +125°C.
