Ceramic Capacitors are non-polarized and fixed value capacitors. In circuits where a small size of capacitor is required Ceramic capacitors comes into picture. These where intially developed in German as replacement for mica. Before 1920's due to insulating properties of mica it was used as a dielectric material in a capacitor. Later, as there was shortage for mica a paraelectric titanium oxide was used as a dielectric which formed the Ceramic Capacitor. The first Ceramic Capacitor was disc … [Read more...]
