Film capacitors, sometimes called polyester capacitors, are small, components used in electrical and electronic equipment to store electrical energy and acquire other desired circuit characteristics. The C4ASPBW3470A3GJ is a type of film capacitor that is designed to achieve high performance and reliability in demanding applications in the entertainment, commercial and industrial sectors. This article will explore the application field and working principle of the C4ASPBW3470A3GJ.

The C4ASPBW3470A3GJ is a film capacitor that is well-suited for applications in the entertainment, commercial and industrial sectors due to its robust construction and high performance capabilities. It is suitable for use in consumer electronics, such as television sets, Hi-Fi systems, audio players and satellite reception systems, where its film dielectric provides high capacitance values, high dielectric strength, good insulation resistance and low dissipation factor. It is also suitable for use in more complex industrial applications, such as in surge suppressors, amplifier circuits, DC/AC converters, power supplies, UPS backup systems and frequency power supplies. The C4ASPBW3470A3GJ is particularly well-suited for switch mode power supplies (SMPS) where its high capacitance values and low ESR provide lower losses and increased efficiency.

The C4ASPBW3470A3GJ works on the principle of capacitance, the ability to store a charge on an insulated conductor. A capacitive device consists of two electrical conductors separated by an insulating material, in this case, a polyester film. When a voltage is applied to the two conductors, an electric field is created that causes an exchange of charge between them. This exchange of charge causes an electrical energy to be stored in the device. This stored energy can then be discharged when there is a change in the applied voltage.

The C4ASPBW3470A3GJ is constructed from an epoxy case layer, a polyester film dielectric, electrolytic foil and an outer aluminum foil. The polyester film provides excellent insulation and has a low dielectric loss factor, which helps to reduce energy losses. The aluminum foil is used to provide a low-impedance connection to the conductors, while the electrolytic grease acts as an interface between the two conductors and prevents corrosion. The epoxy casing helps to protect the internal components from moisture and other environmental factors.

In addition to its application field and working principle, the C4ASPBW3470A3GJ offers a number of other features that make it a suitable choice for demanding applications. It has a long-term stability which helps to maintain its electrical performance throughout its life and a high surge current capability that provides reliable performance in the event of voltage spikes or unexpected changes in the applied voltage.

In summary, the C4ASPBW3470A3GJ is a film capacitor that is well-suited for use in the entertainment, commercial and industrial sectors. It is constructed from a polyester film dielectric, electrolytic foil and an outer aluminum foil and operates on the principle of capacitance. It has a long-term stability which helps to maintain its electrical performance throughout its life and a high surge current capability that provides reliable performance in the event of voltage spikes or unexpected changes in the applied voltage.
