Film capacitors are often used in applications where traditional capacitors such as electrolytic, ceramic, and mica are not suitable. These applications may include radio frequency circuits, power control circuits, precision circuits, and other high-frequency circuit applications. One such capacitor, the “QXK2E473KTP7ZHFJ”, is a film capacitor that is especially well-suited to these types of applications. In this article, we\'ll discuss the application field and working principle of the QXK2E473KTP7ZHFJ film capacitor and how it can be used effectively in different applications.

QXK2E473KTP7ZHFJ is a polyester film capacitor. It is a non-inducting capacitor with a self-healing property, which is its most notable feature. This self-healing property allows the capacitor to operate up to its rated voltage even after it has experienced electrical overstress, making it ideal for high-voltage and high-frequency applications. The QXK2E473KTP7ZHFJ has a voltage rating of up to 1000V, with a capacitance range between 4.7 pF to 470 pF. It is available in various sizes and capacitance values to meet the needs of various applications.

The working principle of the QXK2E473KTP7ZHFJ capacitor is based on a combination of two different principles. The first one is the well-known dielectric layer capacitance. In this principle, two electrodes are placed on two insulated surfaces, which creates an electrostatic field between them, thus providing dielectric insulation to store energy. The second principle is the mechanical force of a metal film as an antioxidant. This film prevents oxidation by creating a barrier between the electrode and the air, thus preventing the formation of corrosion. This combination of dielectric layer capacitance and mechanical force of the antioxidant film creates a capacitor with excellent stability and self-healing properties.

Because of its ideal features, the QXK2E473KTP7ZHFJ film capacitor is suitable for a wide range of applications. These applications include power supplies and controls, high-voltage rectifiers, radio frequency (RF) transmission lines, high-frequency switching applications, ground fault indicators, transient surge suppression, and noise reduction, among others. In addition, the capacitor has excellent long-term stability, low ESR, and good temperature coefficient, making it well suited for precision applications.

The QXK2E473KTP7ZHFJ film capacitor is a highly reliable and cost-effective capacitor which is specially designed for applications requiring high voltage and high frequency. Its self-healing properties make it suitable for a wide range of applications and it is known for its excellent long-term stability and performance in precision applications. In conclusion, the QXK2E473KTP7ZHFJ film capacitor makes an excellent choice for high-voltage and high-frequency applications.
