Bourns CM4030 series common mode chokes

Bourns is introducing the CM4030 series common mode chokes. The CM4030 series offers an inductance range from 2.90mH to 8.90mH and the current range is from 10A to 25A with a footprint measuring 41mm long, 31mm wide, and 40mm tall.

The CM4030 series is designed for filtering common mode noise in a wide range of industrial and commercial applications, such as energy storage, enterprise computing, and green energy. A high permeability nanocrystalline core results in self-resonant frequencies up to 3MHz, making this series ideal for filtering high frequency switching supplies. This series also boasts a robust operating temperature range from -40°C to +125°C.
