ABSTRACT:
An electromagnetic noise filter has a plurality of U-shaped wires passing through a ferrite core. Some of the wires are singly fitted in throughholes, whereas other wires are commonly fitted in throughholes. The wires can be interconnected to provide for impedance to both differential-mode and common-mode noise.
