Different types of capacitors and their significance.

Aluminium electrolytic tantalum ceramic plastic film paper and more. Aluminium electrolytic capacitors have two types foil types and etched foil types. The capacitor has foil plates that are anodized with a dc current. The film capacitor is shown in the figure below.

The electrodes of film capacitors may be metalized aluminum or zinc applied on one or both sides of the plastic film resulting in metalized film capacitors called film capacitors. So the most used names are simply historical. Generally the electrolyte capacitors are used when the large capacitor values are required. The thin metal film layer is used for one electrode and for the second electrode cathode a semi liquid electrolyte solution which is in jelly or paste is used.

Electrolytic ceramic tantalum plastic film youtube. But this is not true for all capacitors because some old electrolytic capacitors are named by its cathode construction. Many capacitors got their names from the dielectric used in them. The different types of capacitors are following.

Silver mica glass silicon air gap and vacuum capacitors. There are two types of film capacitors radial lead type and axial lead type.
