Film capacitors, also known as metallized film capacitors or polyester capacitors, are a type of capacitor that uses thin plastic film as the medium to store electrical charge. The term "film" primarily refers to the type of dielectric used in the construction of the capacitor. The most common type of film capacitor is constructed with a metallized film, with both ends of the film facing inward and each one attached to an aluminum plate. This creates an air gap between the two plates, which is how the capacitance is generated.

The 185153J250RAB-F film capacitor is a product by KEMET, a manufacturer of multilayer ceramic and film capacitors. This particular capacitor is a polyester film capacitor that is said to have excellent characteristics such as low temperature coefficient, excellent humidity resistance, tight tolerance, and high reliability. The capacitor has a rated voltage of 2000 Volts and capacitance of 250 Pico-Farads. It is also available in various sizes.

The application of the 185153J250RAB-F film capacitor can be found in a wide range of industries such as power supplies, frequency correction systems, telecommunications systems, consumer electronics, and signal processing. It is also an ideal choice for use in high reliability and high temperature applications. Its high precision and low ESR make it good performance product, which makes it one of the preferred capacitors of choice today.

In terms of working principle, film capacitors are quite straightforward. When a voltage is applied across the capacitor, the dielectric between the two metal layers will be polarized. This polarization creates an electric field within the dielectrics, which will attract electric charges that will create an electric current. This electric current will build up in the capacitor until the electric field is equal to the applied voltage. At this point, the capacitor has reached its maximum charge and any further applied voltage will cause the capacitor to discharge, thus producing a decrease in the electric current and the electric field.

Overall, the 185153J250RAB-F film capacitor is a reliable and high quality device that can be used in a wide range of applications. Its low ESR and high tolerance make it a reliable choice for various industries such as telecommunications, power supplies, frequency correction systems, and signal processing. This capacitor is also the perfect choice for any application that needs reliable performance and high temperature resistance.
