The characteristics of CIR030-28-22P-F80 can be divided into two parts: application field and working principle.

Application Field

CIR030-28-22P-F80 is typically applied to various types of power electronics applications, including air conditioners, washing machines, refrigerators, gaming machines, chargers, medical equipment, and lighting. In most of these applications, it is used to filter out high-frequency interference, reduce line noise, and suppress transients. It can even be used in audio systems for its excellent filtration effect.

CIR030-28-22P-F80 is used to reduce harmful electromagnetic interference and improve the signal-to-noise ratio of the system. In sensitive electronics, such as medical and gaming equipment where minute details are crucial, the capacitor helps to reduce the risk of malfunctioning due to electrical interference. In some cases, it can even reduce downtime, enabling the system to work more efficiently and reliably.

Working Principle

The working principle of a CIR030-28-22P-F80 is fairly straightforward. It is used to filter out high-frequency noise and transients by allowing only the desired frequencies of current to pass through it. It does this by acting like an electromechanical filter. The capacitor is composed of two plates that are separated by an insulating material called a dielectric. When a voltage is applied to the plates, an electric field is generated that allows the electric current to flow. The capacitance of the capacitor determines the amount of current the capacitor can store.

High-frequency noise and transients are filtered out by the capacitor\'s self-resonance, due to the capacitor\'s imperfect inductance. The AC current entering the capacitor undergoes a phase shift. This phase shift causes a impedance which filters out the high-frequency current and transients from the output. This eliminates the risk of electrical noise from circuits with AC power, improving system reliability.

This type of filter capacitor is also used to regulate the output voltage of circuits, in the presence of large variations in the input line voltage. As the input voltage varies, the capacitor stores or releases charge, which compensates for the input variation, and regulates the output voltage.

In conclusion, CIR030-28-22P-F80 is a general purpose ac line filter capacitor used to filter out high-frequency noise and transients, reduce line noise, and suppress transients, as well as to regulate output voltage. It is used in a variety of power electronics applications, such as air conditioners, washing machines, and medical equipment.
