Film capacitors are a type of capacitor consisting of plastic film and an electrode layer on the two sides of the film. The PME271E622KR30 is a kind of film capacitor manufactured by Cornell-Dubilier Electronics, which has the advantage of high reliability due to its high temperature stable dielectric. In this article, we will discuss the application fields and working principle of PME271E622KR30.

Application Field

PME271E622KR30 can be used in various fields, such as communication equipment, networking systems, electromechanical systems, aerospace and defense systems, automated test equipment, etc. It is particularly used in aerospace and defense applications, because it is capable of withstanding extreme temperature fluctuations. It can be used in high-voltage AC and DC circuits, as well as in frequency conversion systems. It is an ideal choice for applications that require high reliability, high voltage capability, and broad temperature range performance. Moreover, it has excellent pulse handling ability, which makes it suitable for applications with high frequency switching.

Working Principle

The PME271E622KR30 consists of a metalized polyethylene terephthalate (PET) film and electrodes. The electrodes are the conductive layers on the two sides of the film that supply current to the capacitor. The electrodes are usually made of either perforated metal or metalized PET. The PME271E622KR30 also has a dielectric. This dielectric is a material that separates the electrodes and allows the current to flow. The dielectric of the PME271E622KR30 is a high temperature stable polyethylene terephthalate (PET) film. The dielectric of the PME271E622KR30 is designed to provide high reliability and long life in extreme temperatures.

In operation, the PME271E622KR30 acts as a capacitor. This means that it stores electrical energy in an electric field between the two electrodes. When a voltage is applied across the two electrodes, electrical energy is stored in the electric field between them. The amount of energy stored in the electric field depends on the capacitance of the capacitor, which is determined by the physical properties of the film and the electrodes.

The PME271E622KR30 also has a maximum voltage rating. This rating indicates the highest voltage that can be applied across the capacitor without causing any damage. If the voltage exceeds the maximum voltage rating, the electric field will become too strong, which can lead to a breakdown of the dielectric material, resulting in a short circuit.

In summary, film capacitors including the PME271E622KR30 are widely used in various types of electronic equipment due to their high reliability and long life. The PME271E622KR30 is specially designed for high temperature and high voltage applications, and is suitable for applications with high frequency switching. Its maximum voltage rating must be observed in order to prevent any damage to the capacitor.
