Introduction

Film capacitors, also known as polycarbonate (PEN) capacitors, are electrical components used to store electric energy for various applications in electronics. The QXK2J473KTP7FJ is a model of film capacitor, and this article aims to explain its application field and working principle.

Overview of Film Capacitors

Film capacitors are a class of capacitors wherein a dielectric material is sandwiched between two metal plates, which serve as the capacitor’s electrodes. The type of dielectric material can be chosen in order to achieve the desired electrical properties. Generally, film capacitors are characterized by their low equivalent series resistance (ESR), low dielectric absorption, and high ripple current. Additionally, film capacitors typically have a long life span, when compared to other types of capacitors, making them an ideal choice for applications where reliability is of the utmost importance.

QXK2J473KTP7FJ Film Capacitor

The QXK2J473KTP7FJ is a type of film capacitor primarily used in power supply circuits and other high energy-consuming applications. As its name implies, the QXK2J473KTP7FJ capacitor is suitable for use in applications that require high current and voltage, such as those involving welders and electrical motors. Additionally, as the QXK2J473KTP7FJ is a film capacitor, it features lower ESR, higher capacity, and high reliability, as is typical of film capacitors.

Working Principle

The working principle of the QXK2J473KTP7FJ is relatively straightforward. When electric energy is applied to the capacitor, the electrodes generate an electric field, which causes a small amount of charge (Q) to be stored on the plates. The magnitude of the charge that is stored is determined by the capacitance (C) of the capacitor, which is in turn determined by a combination of factors such as the area of the capacitor’s plates, the distance between the plates, and the type of dielectric material used. When the voltage on the capacitor reaches a certain value, the electric field created by the charge stored on the plates will oppose the applied voltage, and the capacitor will reach its maximum capacity. At this point, the capacitor will begin to dissipate the excess energy, and the voltage will decrease as the excess energy is dissipated.

Conclusion

In conclusion, the QXK2J473KTP7FJ is a type of film capacitor, which is primarily used in power supply circuits and other energy-demanding applications. It is characterized by its high current and voltage ratings, low ESR, and high reliability. Additionally, the working principle of the QXK2J473KTP7FJ is directly related to the amount of charge stored on its plates, as determined by its capacitance.
