Abstract
A device that filters electromagnetic interference includes electrical conductors mounted in parallel. Each conductor includes a first coil positioned between a first and a second end of the respective conductor. Each first coil is coupled magnetically to each other first coil and has the same number of turns as each other first coil. The first and second ends of each of the conductors, respectively, are first and second terminals for the device. The device includes capacitors. Each capacitor is mounted between the second end of a corresponding electrical conductor and a third terminal of the device. The device includes an additional circuit. The additional circuit includes a second coil coupled magnetically with the first coils of the conductors. The additional circuit includes an additional coil. The second coil has a second number of turns.
