QYX2A822KTP Datasheet/PDFFilm capacitors
Film capacitors are a type of capacitor composed of a thin plastic film as the dielectric or electrical insulating layer and metalized or foil electrodes. They are constructed by stacking multiple metallic strips covered with plastic films. Because of the excellent performance in terms of quality, low dielectric losses, good stability, long life, film capacitors are widely used for a variety of well-known applications.
QYX2A822KTP application field and working principle
QYX2A822KTP is a type of film capacitor made of polypropylene and metallized film. This type of film capacitor is mainly used for power electronics and telecommunication applications, because of its excellent price/performance index. It has a wide range of working voltages (200V-850V) and capacitance (100pF-2.2uF).
The working principle of QYX2A822KTP film capacitor is essentially the same as that of other types of capacitors. When two charged objects of opposite polarity are placed in the dielectric or electrical insulating layer, the capacitor is formed. A positive charge is attracted to the negative side of the capacitor, while the negative charge is attracted to the positive side. This process is known as capacitance, and it allows the capacitor to store electricity.
In the case of QYX2A822KTP, the metalized film acts as an electrical insulating layer which is divided into two sides. One side is the anode and the other side is the cathode. The electricity is stored in the dielectric layer and when a potential difference is applied between the anode and cathode, current starts to flow between the two sides, thus resulting in the creation of an electric field in the capacitor.
The advantage of using film capacitors in power electronics and telecommunication applications lies mostly in its excellent price/performance index. Film capacitors offer low dielectric losses, good stability and long-term reliability, as well as a wide range of working voltages and capacitances. These qualities make them ideal for these types of applications.
