Film Capacitors and the 104MMR250K Application Field and Working Principle

Film capacitors, also known as plastic film capacitors or film dielectric capacitors, belong to a type of capacitors which use thin plastic films for the dielectric. Film capacitors have high stability, low dissipation factor and a wide range of operating temperatures, making them a reliable device for many commercial, industrial, and military applications. One such film capacitor is the 104MMR250K. This article looks at the application field and working principle of the 104MMR250K.

Applications of the 104MMR250K

The 104MMR250K is a high-voltage film capacitor. It is a product produced by the company Cornell-Dubilier and features a variety of unique features which make it suitable for a range of applications, such as snubber circuits, filters, charge pumps, pulse generators and high frequency amplifiers.The design of the 104MMR250K is based on a combination of thin films of aluminium oxide and modified polypropylene. This combination of materials allows the capacitor to provide very high stability, low dissipation factor, and a wide range of operating temperatures. It is also capable of handling high voltages of up to 750 volts.The 104MMR250K is physically small in size, measuring just 104mm in length and weighing 25g. This makes it ideal for use in applications where space is at a premium, such as in mobile or portable devices.

Working Principles of the 104MMR250K

The 104MMR250K is a non-electrolytic capacitor. This means that it does not use an electrolyte, such as liquid or paste, as the material for its dielectric field. Instead, it uses thin films of aluminium oxide and modified polypropylene as its dielectric.The aluminium oxide films used on the 104MMR250K are both gas-impermeable and liquid-impermeable, providing excellent insulation properties even when used at high voltages. The films are also resistant to thermal shock, mechanical damage and the effects of ageing. The capacitor works by storing electrons on the surface of its dielectric material. As electric current is passed through the capacitor, electric charges build up on opposite sides of the device. This creates a potential difference between the two sides, which creates the effect of a capacitor.The 104MMR250K can also be used in conjunction with other components, such as transistors and resistors, to create a variety of electric circuits. These circuits can be used for a range of applications, such as power supplies to electric motors, amplifiers and control systems.

Conclusion

The 104MMR250K is a versatile and reliable high-voltage film capacitor produced by Cornell-Dubilier. It features a unique combination of materials which make it suitable for applications in snubber circuits, filters, charge pumps, pulse generators and high frequency amplifiers. Its small size and wide operating temperature range make it particularly well-suited for use in mobile or portable devices. Finally, its working principle relies on electric charges building up on opposite sides of its dielectric, which can then be used in electric circuits for a variety of applications.
