Abstract

See full text

A circuit interrupting device such as a GFCI having a network of feed-through capacitors and other passive elements for providing enhanced Radio Frequency Interference (RFI) suppression where the feed-through capacitors and the other passive elements are integrated into a multilayer capacitor chip, also referred to as a Network Capacitor which is located between a differential transformer and at least one input terminal of an operational amplifier on an integrated circuit chip of the GFCI circuit.
