WebJan 25, 2024 · This is indeed a common mode choke. It basically consists of 2 identical coils sharing the same core so that their magnetic fields are coupled. The ferrite core enhances the magnetic coupling and increases inductance which makes the coil's impedance higher for high frequencies. That means it becomes more effective as a filter. http://www.pmillett.com/DC_filament_supply.htm
