Film Capacitors have been a staple of the electronics industry for many decades. PME271E547MR30 film capacitors are a popular choice for applications in a variety of industries and devices, from consumer electronics to industrial automation systems. This article will explain the application field and working principle of this model of film capacitor.

Types of Film Capacitors

Film capacitors are constructed using multiple layers of thin, insulating materials that are rolled up into the shape of a cylinder. Depending on the type of materials used in the construction process, there are several different types of film capacitors available on the market today including polyester, polypropylene, PTFE, polycarbonate, and polystyrene.

PME271E547MR30 film capacitors are constructed with polyester film, making them highly reliable and stable, with excellent electrical and dielectric characteristics. They are particularly suitable for use in high frequency, high voltage applications and can be used in a variety of environments.

Application Field

PME271E547MR30 film capacitors are suitable for a variety of different applications, including audio equipment, power supplies, motors, automotive electronics, and industrial automation systems. They can be used as an energy storage device or as an energy filter in low-frequency circuits. They are also used for high-frequency snubber circuits, over voltage protection in power supplies, and in switching circuits.

The PME271E547MR30 has a rated voltage of 275V, a capacitance of 0.047 µF, and a capacitance tolerance of +80% / -20%. This means that the capacitor is suitable for use in high voltage and high frequency circuits, while maintaining a stable and reliable performance. It also has a low ESR (Equivalent Series Resistance) and high self-resonance frequency, making it a powerful choice for a variety of applications.

Working Principle

The working principle of film capacitors is relatively simple. A film capacitor is an electronic component that consists of two electrical conductors that are separated by a dielectric (insulating) material. When a voltage is applied across the conductors an electric field is created between them. The electric field then increases the capacitance of the film capacitor.

This increase in capacitance is the result of the electric field causing more electrons to be “pushed” into the dielectric material between the two conductors. This increase in electrons leads to a higher capacitance value, which essentially “stores” the electric energy. When the voltage across the conductors is removed, the electric field also collapses and the stored energy is released.

It is because of this ability to “store” electric energy that PME271E547MR30 film capacitors are popularly used in high voltage, high frequency circuits. This type of film capacitor is also highly reliable and stable, and can withstand operating temperatures ranging from -40°C to +105°C.

Conclusion

In summary, PME271E547MR30 film capacitors are a reliable and popular choice for a variety of applications including audio equipment, power supplies, motors, automotive electronics, and industrial automation systems. Their working principle is based on the ability to “store” electric energy when a voltage is applied across the conductors, which is then released when the voltage is removed. With its rated voltage of 275V, a capacitance of 0.047 µF, and a capacitance tolerance of +80% / -20%, the PME271E547MR30 is a powerful choice for a variety of high voltage, high frequency circuits that require a stable and reliable performance.
