Common Mode Power Line Choke - WE-CMBH

Common Mode Power Line Choke for ultra-slim products

With the WE-CMBH series Würth Elektronik now also offers a common mode power line choke in a horizontal version. With a profile height of only 22 mm the power line choke is ideal for slim housings.

Due to low-capacitance winding technology, suppression over a wide band is now possible. This makes the WE-CMBH an excellent choice for interference suppression in the frequency range from 150 kHz to 30 MHz.

The product is available with inductance values from 1 mH up to 7 mH with a nominal current of up to 10 A.

In power electronics the WE-CMBH is used as power filter and output filter as well as in motor interference suppression. Würth Elektronik specifies the operating temperature range as –40 to +125 °C.

Characteristics:

horizontal design for compact housings
suppression even at low frequency ranges
broadband screening because of low capacitance winding technique
highest possible current with small sizes
customer specific designs on request
operating temperature: -40°C to +125°C

Applications:

Power electronics
Power line in- and output filter
Radio interference suppression in motors
suppression for common mode noise
