Film capacitors are particular capacitors which use thin plastic or paper film as the dielectric material. It provides higher capacitance per unit volume and a wider working temperature range than electrolytic or ceramic capacitors. Film capacitors are divided into Metallized Film Capacitor, Polyester Film Capacitor, Polypropylene Film Capacitor, Polystyrene Film Capacitor and Paper Film Capacitor.

ECW-HA3C622H is a metallized polyester film capacitor which is one of the most popular film capacitors. It is tight-roll aluminium foil with polyester film as dielectric and can be used in the following applications:

• Used as the AC line filter with the operating temperature of -40℃ - +105℃.
• Used in the audio frequency circuit (VCD, DVD), and other electronic products.
• Used in wide range of electronic circuits and electronic equipment where the high stability, low dissipation and high insulation characteristics are required.
• Used in the air conditioner, washing machine, DC motor and other household appliances.

The construction of ECW-HA3C622H consists of two pieces of aluminium foil with film insulation as dielectric layer. The two pieces of aluminium foil are then wound in a roll. The construction of the ECW-HA3C622H metallized polyester film capacitor ensures that all of its components are strongly connected, effectively preventing electrical breakdown, pressure, temperature and shock.

The working principle of film capacitor is based on conservation of charge. The charge on the capacitor plates is conserved and the current only flows when an electrical potential difference is applied. The potential difference generates a Coulomb electric field between the capacitor plates, resulting in electrostatic induction. The electric field produces an electric potential and the current will flow in the conductor, thus transferring the charge and resulting in an electric current.

In ECW-HA3C622H metallized polyester film capacitor, the charge is conserved in the form of electric energy stored in the dielectric layer of the capacitor. As a result, when a potential difference is applied, charge will be transferred from one plate to the other plate, resulting in electric current flowing through the capacitor, thus allowing for effective and efficient energy transfer.

In conclusion, ECW-HA3C622H metallized polyester film capacitor has wide range of applications and working principle is based on the conservation of charge. The construction and design of ECW-HA3C622H ensures that all of its components are correctly connected and effective prevention of electrical breakdown. Therefore, it is suitable for use in the audio frequency circuit, AC line filter, air conditioner and other electronic products.
