Film Capacitors

Film capacitors are components designed to store energy in the form of charged particles within the thin films of dielectric material. These capacitors employ a wide variety of materials and constructions depending on the requirement specifics, such as temperature and voltage ratings. One type of stand out film capacitors is 185272J100RAA-F, employed in many industrial applications.

Application Field

185272J100RAA-F has a broad range of application. It is a mid-voltage film capacitor featuring high insulation, low ESR and a wide temperature range making them suitable for a variety of power applications, such as power factor correction, energy storage, switching power supplies, and high-frequency welding among others.

Additionally, this capacitor type enhances the durability of electrical products and enhances product safety by eliminating the need for additional insulation. They also help reduce or mitigate the current ripples, low frequency noise, and common-mode interference in the power systems.

Working Principle

When a voltage is applied to the capacitor poles, the positive charges on the inside of the capacitor are attracted to the negative charges on the outside of the capacitor, creating a distorting effect on the dielectric material between the electrodes. This distortion decreases the effective capacitance of the component. This distortion resonates through the dielectric material resulting in varying levels of distortion. Repulsion between the particles then increase, causing a decrease in the capacitance.

This type of capacitor utilizes dielectric material consisting of thin metallic films that are coated with a non-conductive material. This configuration reduces the component’s size and increases the capacitance as the film thickness increases. Moreover, the dielectric layers of a film capacitor are composed of a dielectric material that has a higher permittivity than air or vacuum, leading to improved efficiency.

The major downside of this type of capacitor is that it is much bigger than aluminum electrolytic capacitors, so when there is not enough space to host a film capacitor most engineers go with an aluminum electrolytic.

Conclusion

185272J100RAA-F capacitors are a great choice for many applications due to their reliability, durability, and efficiency. Film capacitors are able to provide excellent performance at any temperature and voltage, making them an ideal choice for a range of industrial applications. They are also an economic option, offering great performance at a relatively low cost.
