Disc Type Capacitor is constructed by covering two sides of a tiny porcelain or ceramic disc with silver and stacking them together to form a capacitor. A single ceramic disc of roughly 3 to 6mm is utilised for some very low capacitance values. This type of capacitor has a dielectric constant and is accessible in tiny physical sizes, allowing for comparatively high capacitances. Disc Type Capacitor ranges in size from a few picofarads to one or two microfarads, although their voltage ratings are often modest.
