Some common mode choke coils are applied in circuits linked to AC power lines (commercial power lines), like the primary side of switching power supplies. Common mode choke coils utilized in these locations are frequently known as "line filters".

These common mode choke coils are utilized along with over the line capacitors (X-capacitors) and line bypass capacitors (Y-capacitors), and are utilized to prevent noise generated through the secondary side circuit from dripping towards the primary side, and also to prevent noise generated through the power circuit from getting away through the cord.

Common mode chokes and Line bypass capacitors remove common mode noise, while over-the-line capacitors remove differential mode noise. Growing the capacitance of a line bypass capacitor causes elimination of lower frequency common mode noise, however the chance of current leaking to the ground expands along with the capacitance, to ensure the capacitance need to be detained to a certain value or less.

That is why, common mode choke coils are mostly employed in the low-frequency selection that can not be insured by line bypass capacitors. Additionally, the application of normal mode choke coils are able to provide enhanced differential mode noise removal results in some instances.

Token will also produce devices outside these specifications to meet customer requirements, with comprehensive application engineering and design support available for customers worldwide.
