Bourns CM4030 Common Mode Chokes

Bourns CM4030 Common Mode Chokes offer a nominal inductance range from 2.90mH to 8.90mH and a current range from 10A to 25A. These chokes feature a high-permeability nanocrystalline core, resulting in self-resonant frequencies of up to 3MHz. The CM4030 common mode chokes are designed for filtering common mode noise in a wide range of commercial and industrial applications. These chokes are ideal for filtering high-frequency switching supplies with temperature ranges from -40°C to 125°C. The CM4030 common mode chokes feature an energy-saving low power design and meet EU 94/62/EC standards. These chokes are certified with Moisture Sensitivity Level (MSL) 1 and are RoHS compliant. Typical applications include AC power supplies, AC input filters, DC power converters, and general EMI.
