ABSTRACT:
A trimmer capacitor includes an insulating substrate having recesses to accommodate a dielectric member having the stator electrode printed thereon. A terminal is soldered to the stator electrode and fits within a recess of the insulating plate. A rotor electrode is provided over the dielectric member. The dielectric member does not itself need to be rotated and is adequately supported and thus can be made quite thin even if brittle dielectric material such as titanium dioxide or barium tatinate is used.
