Power line filter modules are modularized passive component assemblies that are used to inhibit current flow through power supply conductors at frequencies outside that which is nominal for the intended supply. Commonly used in conjunction with AC utility power sources, they are used both to mitigate interference caused by outside sources as well as suppress potential interference which might be caused by a connected device.
