Film Capacitors

A film capacitor, also known as a plastic film capacitor, is a type of capacitor that consists of a plastic film as one of its capacitor plates, so the name film capacitor, and the other plate is a metal layer — typically aluminum, copper, or zinc on top of which the dielectric is applied. Commonly-used dielectrics for film capacitors are polyester (Mylar), polypropylene, and polystyrene materials. In the case of the 168104J250G-F, a polyester film is used.

Applications

Film capacitors have many applications due to their excellent electrical properties. Some of the most common uses of film capacitors are as coupling capacitors in audio systems, radio receivers and transmitters, for power factor correction in AC/DC circuits, and for lightning protection in wind turbines. They are widely used in the automotive and industrial sectors, and medical equipment also makes good use of them. The 168104J250G-F is specifically designed for any pulse, high frequency or DC application with long-term stability.

Working Principle

The working principle of a film capacitor is based on the electrostatic principle and the parasitic capacitance between two plates. A dielectric medium, usually an insulating material such as a plastic film, is sandwiched between the two plates such that the plates are insulated from each other and the electric field is contained inside the dielectric material. When a voltage is applied across the capacitor plates, the electric field generated inside the dielectric induces a polarization of its molecules, thus creating a force between the positive and negative charges. This force causes the charges to accumulate on the capacitor plates, which in turn stores electrical energy.The 168104J250G-F has a unique construction with two units connected in series. This ensures a higher current load capacity and greatly reduces the effect of dielectric absorption and makes the product especially suitable for communication equipment.

Conclusion

Film capacitors are widely used for various kinds of applications because of their excellent electrical properties and ability to store electrical charge. The 168104J250G-F is one such film capacitor, specifically designed for use in pulse, high frequency and DC applications with long-term stability and high current load capacity. The capacitor works on the basis of the electrostatic principle and the parasitic capacitance between two plates, with a dielectric medium acting as an insulator between them.
