Film Capacitors

---

Film capacitors are two-electrode electrical capacitors that are either manufactured from polyethylene terephthalate (PET) films or a combination of other thin plastic films such as polyester or polyphenylene sulfide (PPS). These capacitors are used many industries including automotive, aerospace, medical, telecommunications, consumer electronics, and industrial.

These capacitors are commonly used in power conditioning and electrical filter networks, AC bypass circuits, and general power decoupling. Capacitors with this type B32641B6473J can be found in various electronic and electrical products, including televisions, cellular phones, air conditioners, refrigerators, and other home appliances. In the automotive industry, film capacitors with this type B32641B6473J are used in fuel injection systems, spark gap units, electronic speedometers and start/stop systems.

Working Principle of Film Capacitors

---

At the heart of a film capacitor is the dielectric material, which is typically made from a thin film of plastic such as PET or PPS. Between the two electrode surfaces of the film capacitor is an insulating dielectric material such as air, ceramics, and other non-metallic materials. When voltage is applied to the two electrodes, electric fields are established in the dielectric material, which then stores electric energy. The electric energy stored in the dielectric film is proportional to the surface area of the capacitor’s electrodes, as well as the capacitor’s capacitance. The capacitance of film capacitors is determined by the number of parallel layers of dielectric and the distance between electrodes. The capacitance of a film capacitor also decreases with a rise in temperature, which results in a reduction in capacitance.

Advantages of Film Capacitors

---

Film capacitors offer a lot of advantages over other types of capacitors. One of the main advantages of film capacitors is their high dielectric strength, which provides them with superior performance over ceramic or electrolytic capacitors. They also have low dissipation and low leakage currents, and they can be used in a wide range of applications due to their flexibility and ability to handle high temperatures. Finally, film capacitors are highly reliable and very durable, allowing them to be used in highly reliable systems.
