Common mode chokes are usually based on high permeability ferrite toroids with at least two symmetrical windings. The operating current flows through them in such a way that the magnetics fields cancel each other out. The operating current is only affected by the low stray inductance of the windings. If the currents in the windigs are different, because of asymmetric interference, a high inductance works on the differential current.   more ...

These common mode chokes are based on high permeability nanocrystalline toroids with at least two symmetrical windings. The operating current flows through them in such a way that the magnetics fields cancel each other out. The operating current is only affected by the low stray inductance of the windings. If the currents in the windigs are different, because of asymmetric interference, a high inductance works on the differential current.   more ...

These chokes are based on iron powder toroidal cores from Micrometals 26 material. Because of their distributed air gap they have only little inductance dependence on DC magnetization and they can be used e.g. as the switch-source filtering chokes with work frequencies up to hundreds kHz.   more ...

These chokes are usually based on alloy powder cores with Sendust material. Compared to the iron powder cores, they have slightly larger inductance dependence on DC magnetization. However their main advantages are much better frequency properties, which predestined them to use as the switch-source chokes to frequency at least 100 kHz.   more ...
