Trimmerkondensatoren gleichen Kapazitäten in Schaltungen aus
Trimmerkondensatoren sind in der Rundfunktechnik weitverbreitet und dienen als Drehknöpfe zur Sendereinstellung. Die Kapazität der Trimmerkondensatoren lässt sich innerhalb definierter Grenzen mechanisch stufenlos einstellen. Hergestellt sind diese aus zwei halbkreisförmigen Plattenpaketen mit isolierender Schicht aus Luft oder Kunststoff. Durch Drehen an der Einstellschraube kann das bewegliche Plattenpaket hinein- oder ausgedreht werden.
