Introduction to Film Capacitors

Film capacitors are electrical capacitors consisting of two metallic foils separated by a dielectric. They are also known as plastic film capacitors due to the fact that the dielectric material used is generally a plastic film, most often polyester. Due to their low dissipation factor (E6) they are commonly used in high-end audio and video equipment.Film capacitors are highly efficient components used for applications that require stable voltage and current regulation, such as power supplies or AC/DC converters. They can also be used for various other purposes such as bypass, coupling, and decoupling. Film capacitors come with a variety of different styles and configurations, making them very versatile components.

B32537B1104K Application Field and Working Principle

The B32537B1104K film capacitor is an epoxy encapsulated, radial leaded high-voltage film capacitor. It is a non-inductive type and ideal for use in most applications requiring high stability and capacitive performance, such as suppression, coupling, and decoupling. The B32537B1104K has an ESR of 0.01 ohms and a capacitance range up to 4.7 microfarads.The B32537B1104K is also very reliable, with a maximum operating temperature of 85°C and a life expectancy of over 5000 hours at 20°C. It features an extremely low ESR rating. The capacitance of this film capacitor is also self-healing, meaning it has the ability to repair itself after being damaged by electrical impulses, making it a suitable choice in applications where high voltage transients or surges may occur.The B32537B1104K film capacitor works through the principles of dielectric absorption. The dielectric absorbs electrical energy and prevents it from returning to the circuit, preventing overshoot, undershoot, and other voltage irregularities. It also releases the absorbed energy as the alternating voltage changes, providing a smooth current flow as voltage and current alternate in the circuit. The efficient circuitry design enables this film capacitor to reduce the heat generated during operation, making it an ideal choice for applications with strict thermal management requirements.

Conclusion

Film capacitors are widely used in many industries, including power supplies, AC/DC converters, audio and video equipment, and automotive applications. The B32537B1104K is an example of a film capacitor with excellent characteristics, including a low ESR rating, high stability and reliability, and self-healing capacitance. The dielectric material of the capacitor absorbs electrical energy and releases it as the voltage changes, providing a smooth current flow to the circuit. The efficient circuitry design of the film capacitor also keeps it from generating excess heat during operation.
