ABSTRACT:
A miniature multi-impedance transformer module specially adapted for use in telephony. In the preferred embodiment a pair of multi-winding transformers and a coil are configured to have connecting pins projecting both above and below the bodies thereof. The upward projecting pins are inserted in a printed circuit board carrying a plurality of connectors in a predetermined array. This assembly is installed in a miniaturized case and potted in place with the lower projecting pins extending below a mounting surface of the case. The lower surface and the downward projecting pin are adapted for ready mounting on a second printed circuit board. The connectors at the top of the module receive shorting plugs for selectively connecting the windings of the transformers and coil to provide impedance matching in telephone equipment. The miniaturized board mounted modules are readily adapted for high density rack mount applications.
