What is the difference between thin film capacitor and electrolytic capacitor?
Visit:3886 Date:2019-03-07
Film capacitor: A film capacitor is a capacitor in which a metal foil is used as an electrode and a plastic film such as polyethylene, polypropylene, polystyrene or polycarbonate is stacked from both ends and wound into a cylindrical structure.

Electrolytic capacitor: Electrolytic capacitor is a kind of capacitor. The metal foil is a positive electrode (aluminum or tantalum). The oxide film (aluminum oxide or tantalum pentoxide) which is in close contact with the positive electrode is a dielectric. The cathode is made of a conductive material and an electrolyte. It is a liquid or solid) and is composed of other materials. Since the electrolyte is the main part of the cathode, the electrolytic capacitor is named after it.

At the same time, the electrolytic capacitors are not connected correctly. Aluminum electrolytic capacitors can be divided into four categories: lead-type aluminum electrolytic capacitors; horn-type aluminum electrolytic capacitors; bolt-type aluminum electrolytic capacitors; solid aluminum electrolytic capacitors.
