Film Capacitors

Film capacitors are a type of capacitor which uses a thin plastic film as its dielectric. The film is usually made from polymer, such as a polyethylene terephthalate (PET) or a polycarbonate (PC). The film provides insulation and dielectric strength, and the metal plates used on either side of the film provide conductivity. Film capacitors can be used in a variety of applications and are a great choice for high voltage and high frequency applications.

B32654A1473K189 application field and working principle

The B32654A1473K189 film capacitor is a type of metalized polyester film capacitor which is ideal for use in high frequency and high voltage applications. It features a capacitance of 0.47 μF, a tolerable maximum operating temperature of 105℃, and an insulation resistance of 1.00 MΩ. It is also UL recognized and UL94V-0 certified. This capacitor is commonly used in motor controls, switched mode power supplies, electronic ballasts, and audio/amplifier circuits.

The B32654A1473K189 works by storing electrical charge between two metal plates which are placed close together. As current passes through the device, the plates create an electrical field and a capacitance. The amount of capacitance depends on the size of the plates, their spacing, and the dielectric material used. Since film capacitors use a thin, dielectric film, they are able to store and release energy more efficiently than other types of capacitors.

The B32654A1473K189 is able to provide high capacitance in a small form factor, making it an ideal choice for applications where space is limited. The film construction also helps to reduce noise and reduce electrical interference, making it suitable for sensitive applications. Additionally, the film construction helps to reduce the overall size and weight of the capacitor, making it easier to handle and store.

In summary, the B32654A1473K189 is a type of film capacitor which is ideal for use in high frequency and high voltage applications. It features a capacitance of 0.47 μF, a maximum operating temperature of 105℃, and an insulation resistance of 1.00 MΩ. It is UL certified and works by storing electrical charge between two metal plates which are placed close together. The thin film construction helps to reduce noise and interference, reduce size and weight, and increase capacitance in a small form factor.
