Mode Chocks

To Create Line Filter Circuits

In combination with the necessary capacitors, common mode chokes are used to create line filter circuits, to suppress the radiation of internal noise from the device and to prevent the infiltration of external noise from the power network. The symmetrical interference often occurs in addition to asymmetrical interference in nearly all devices containing a protective conductor terminal such as electronic ballasts or electrical tools. This requires additional inductance. Common mode chokes suppress both types of interference. By using special common mode chokes with bypass the extra coil can be avoided. This saves customer design costs and the existing space on the PCB can be retained.

CODICO offers a wide range of common mode chokes with different sizes and for a variety of current levels.
