Film Capacitors

Film capacitors, alternatively known as plastic film capacitors or dielectric film capacitors, are widely used for a range of electronic applications due to their superior electrical characteristics and low price point. Based on a polyethylene terephthalate (PET) film as the dielectric material, the capacitance of film capacitors is developed by the surface area of the metal film layered onto the PET material. This is impregnated with oil to provide improved insulation and heat transfer characteristics. For this reason, film capacitors are generally sold as two distinct types: oil filled film capacitors and dry film capacitors.

185104K50RAA-F Application Field and Working Principle

The 185104K50RAA-F is an oil filled film capacitor developed and manufactured by the US manufacturer Kemet. This component is designed for AC, DC, AC/DC, RF, Microwave, Resonance, Pulse, and Switching applications. It is part of the company’s standard RADIAL capacitor series. The component is composed of a metallic film secured to dielectric material such as PET. It also contains a wire-wound element which is designed to minimize any electrical losses.

The 185104K50RAA-F has a maximum capacitance of 0.5uF, with a range of voltage ratings up to 500V. It also has a frequency range of up to 3MHz and a temperature range of -55C to +130C. The component is designed for operation in environments with vibration, shock, and other mechanical stresses. It also offers increased safety due to its built-in thermal fuse.

In addition, the component is designed with a standard radial lead configuration to make it easier to install and connect with other capacitors. It is also designed for low-ESR applications, which means that it has a low impedance drop rate, providing improved power efficiency and better performance. The component is also designed to reduce noise and ripple, providing improved reliability for sensitive electrical components.

The working principle of the 185104K50RAA-F is based on its dielectric material and metal film design. When a voltage is applied, the electric field between the film and dielectric material creates an electric charge that stores energy. This energy is then released once the voltage is removed from the component, creating a large current surge as the charge is discharged.

Overall, the 185104K50RAA-F component is a reliable and cost-effective solution for a range of electrical applications. Its design makes it suitable for both DC and AC applications, and its low ESR properties mean that it can be used with improved performance. This makes it an ideal choice for applications which require reliable capacitance.
