Film capacitors are one of the most popular capacitor types. They are known for their ability to handle large amounts of voltage and current, their excellent durability, and their wide range of applications. The PME271YA4470MR19T0 is a film capacitor that has gained much popularity among industry professionals for its performance and dependability. In this article, we will cover the application field and working principle of the PME271YA4470MR19T0.

What are Film Capacitors?

Film capacitors are electric components made with a thin sheets of dielectric film that is typically polypropylene or polyethylene. This film serves as the capacitor’s dielectric, or insulating material, and is usually flanked by two metal or aluminum plates called “plates”. Film capacitors can come in different shapes, such as cylindrical, rectangular, and even waffle-shaped. The prime advantage of film capacitors is their higher working temperature, up to 100°C. This temperature capacity makes them particularly useful in a wide range of applications, such as AC/DC power supplies, converters, discharge lamp drivers, and motor speed controllers.

PME271YA4470MR19T0 Application Field and Working Principle

The PME271YA4470MR19T0 is a low cost, long life and high performance film capacitor that is used in a variety of applications. It is a polypropylene film capacitor that is able to operate at temperatures up to 30kV, with a capacitance range of 0.22µF - 4700µF, a temperature coefficient range of ±25ppm/°C, and a wide temperature range of -55°C—+105°C. It is also constructed with nonpolar and noninductive construction, which makes it suitable for different kinds of applications such as power supplies, uninterruptible power supplies, welding equipment, and audio/radio circuits.

The working principle of the PME271YA4470MR19T0 is quite simple. When an electrical voltage is applied across the plates of the capacitor, the film dielectric is polarized by the electric lines of force in the line and creates a small electric field within. This electric field stores energy and introduces capacitance to the circuit in which it is incorporated. The capacitance value of the capacitor will depend on the size and shape of the dielectric film, as well as the surface area of the plates exposed to the electric field. The higher the surface area of the plates, the larger the capacitance value of the capacitor becomes.

Conclusion

The PME271YA4470MR19T0 is a film capacitor with exceptional performance and dependability. It is capable of handling large amounts of voltage and current and has a wide range of applications, from AC/DC power supplies to welders and audio/radio circuits. It is also able to operate at temperatures up to 30kV, and its nonpolar and noninductive construction make it suitable for many different kinds of applications. We hope that this article has provided you with some useful information about the PME271YA4470MR19T0 application field and working principle.
