The Wurth Elektroniks common mode power line choke used for mains power line-in and out filter, power electronics. It is also used for filtering of devices without any ground connection, suppression of radio interferences in motors and for suppression of common mode noise. It is made of MnZn.

Broadband filtering due to low capacitance winding technique
High suppression of asymmetrical interferences also at low frequency
Very compact design and high rated current of 7.5 A at 70 °C
DC resistance of 10 mΩ at 20 °C
Operating temperature of -40 ºC to +125 ºC
