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.
