ABSTRACT:
Four-terminal type noise filter having a first strip-like conductor with first inner and outer input/output leads each connected to the first conductor adjacent each end, a second strip-like conductor with second inner and outer input/output leads each connected to the second conductor adjacent each end, and dielectric sheets superimposed on the respective strip-like conductors. The sandwich of conductors and dielectric sheets are rolled into a flat tube such that the first and second inner leads defines a set of input and output terminals and said first and second outer leads defines another set of input and output terminals. The filter positively minimizes noise received by the filter without creation of ringing.
