Abstract
A complex circuit component for a video signal circuit in a television receiver set has a single substrate, on which a first ceramic trap for removing speech carrier wave together with an inductor for that trap, a second trap for removing color subcarrier wave, and a delay circuit coupled with output of said second trap are mounted. The capacitors for those circuits are implemented by a pair of conductive patterns deposited on front surface and rear surface of the substrate. The capacitor for said first ceramic trap is subject to trimming so that the characteristics of the trap is adjustable.
