Film capacitors, commonly known as plastic film capacitors, refer to capacitors whose dielectric is a thin film made of plastic, such as polyester film, polypropylene film and polystyrene film. They are divided into three categories: film capacitors, metallized capacitors and foil capacitors. ECW-U2563KC9 is a kind of film capacitor usually used in various electrical, electronic and telecommunications equipment. This article will focus on ECW-U2563KC9, including its application field and working principle.

First of all, the application field of ECW-U2563KC9 is widely. It is mainly used in the fields of ac power, filter system, vcd, dvd, digital products, home appliance, sound system, computer, etc. This kind of film capacitor usually equipped with various electrical and electronic devices and widely used in ir photography machines, black lights, frequency converters, circuit breakers, electronic keyboards, high voltage dust remover, arc generators, are welding and other fields.

The working principle of ECW-U2563KC9 can be summarized as follows. When two terminals of the capacitor are connected with DC power supply, the positive electrode attracts the negative electrode, so that the capacitor begins to charge until the positive electrode and the negative electrode exchange their charges. Then the capacitor will generate an electric field between the electrodes, which results in a capacitance. After the capacitor is fully charged, no current is present in the circuit.

In order to increase the capacitance and reduce the size of the film capacitor, it is generally constructed in layers that are oppositely charged to each other. A metallized paper, polypropylene film or polyethylene terephthalate film is used between two conductive plates, and these conductive plates are the two electrodes of the film capacitor. And electrostatic attraction forces the film to form a stable electric field between these two plates.

In addition, in order to reduce the dielectric loss, generally an insulating layer is added to the gap between the electrodes, which is also known as DC bias. In this case, the electric field between the two plates will be more stable and the dielectric constant will gradually increase, so that the product performance will be more excellent.

In conclusion, ECW-U2563KC9 is one kind of film capacitor, which has wide application fields and can be used in many electrical, electronic and telecommunications equipment. In general, it is composed of two conductive plates and an insulating layer sandwiched in between. It consists of positive electrode, negative electrode and electric field, which can store dielectric energy and provide electric current. Therefore, film capacitors can be used for general purpose filter, dc circuit, power supply, switching power supply, amplifier and other purposes.
