Film capacitors are one of the most important components for many electronic applications because they are highly reliable, space saving and cost-efficient. The FCN2420E823K-B belongs to this group of components. This article will discuss the application field and working principle of FCN2420E823K-B.

Application Field

The FCN2420E823K-B offers designers excellent performance for a variety of applications, such as power supplies, uninterrupted power systems, and circuit protection. Its main feature is the high current capability, which is important for the reliable operation in these applications.

The FCN2420E823K-B is also widely used in audio and audio-related applications, such as amplifiers, audio equalizers, high-end mixing consoles, and effects pedals. This capacitor provides outstanding frequency response and exceptional audio clarity, making it the ideal choice for these applications.

In addition, FCN2420E823K-B is widely used in RF applications for its low ESR, low dissipation factor, and excellent frequency response. It is commonly found in antenna tuners, wireless receivers, and oscillators.

Working Principle

The working principle of the FCN2420E823K-B is essentially the same as other film capacitors. An electric field is created between two thin metal plates (generally aluminum or tin) and the dielectric is inserted. The electric field induces an opposite voltage in the dielectric material, which creates a capacitor.

The capacitor stores energy in the electric field between the plates. When a voltage is applied to the capacitor, the electric field increases, causing the stored charge to increase. When the voltage is removed from the capacitor, the electric field decreases and the stored energy is released.

The FCN2420E823K-B is a non-polarized, low-leakage, and temperature-stable capacitor. Its low-leakage feature minimizes the amount of energy that is lost over time, making it better at holding charge. The temperature-stability feature ensures that the capacitance is not affected by fluctuations in temperature.

Unlike ceramic and electrolytic capacitors, film capacitors are much sturdier and less susceptible to external influences. This makes them a better choice for applications that require high reliability and stability.

The FCN2420E823K-B is a reliable and efficient capacitor for a variety of applications. Its key features, such as high current capability, low leakage, and temperature stability, make it an ideal component for audio, RF, and power supply applications.
