DC Line Common Mode Chokes
About this series
DC Line Common Mode Chokes are wound magnetic components designed to suppress common-mode noise on DC power lines. They block high-frequency interference from coupling between supply and return paths while presenting low impedance to the desired DC current. Used downstream of switching converters and upstream of sensitive loads.
Features
- Toroidal or two-coil construction
- High common-mode impedance across MHz–GHz range
- Low DC resistance for minimal power loss
- Operating temperature range suitable for industrial / automotive environments
- RoHS / REACH compliant
Common Applications
- Industrial DC bus filtering
- Automotive 12V / 24V / 48V power systems
- Renewable energy DC link (solar inverter / EV charger DC stage)
- Telecom / data center backplane power
- Medical equipment DC input filtering
