Film capacitors, also known as plastic film capacitors, polypropylene film capacitors or film dielectric capacitors, are electrical components that can store electrical charges, store energy in an electric field and discharge it, and provide a high-impedance connection to block AC signals. PVC16122 is a film capacitor developed by HOMYQ. It is a polypropylene polymer film capacitor featuring high insulation and high reliability. Below, we discuss the application field and working principle of the PVC16122 film capacitor.

Application field

PVC16122 film capacitors are often used as filtering or bypassing elements in electronic circuits, such as integrating amplifiers, general circuits, voltage-controlled oscillators, and so on. They are also used in situation where huge AC/DC voltage may arise, such as switching power supply, welding machines, AC motor drives and so on. The PVC16122 film capacitor exhibits good temperature resistance, durability to withstand harsh environments and excellent EMI suppression. Therefore, it is widely used in all kinds of industial applications including comminication systems, consumer devices, household appliances, medical equipments, automobile electronic systems and so on.

Working principle

The PVC16122 film capacitor uses a thin plastic film as the dielectric material, sandwiched between two metal plates. As a capacitor, the main task is the storage and discharge of electrical charge. PVC16122 film capacitors have two electrodes that are electrically separated from each other by the plastic dielectric film. When a voltage is applied to the two electrodes on the capacitor, current will flow between the two electrodes. The amount of charge that can be stored depends on the capacitance of the capacitor, which is determined by the thickness of the dielectric material between the electrodes as well as the area of the electrodes. As the capacitor stores charge, an electric field is created between the two electrodes, and this field stores the energy. When the voltage across the capacitor is reduced or removed, the electric field between the electrodes collapses and the energy stored is released.

PVC16122 film capacitors are able to filter high frequency noise. This is achieved by the electrons crossing the dielectric film and causing the capacitance to spike and then slowly decrease again. As the capacitance spikes, the signal is blocked and high frequency noise is filtered. This is a very useful feature when EMI noise reduction is required.

In summary, PVC16122 film capacitors are widely used in all kinds of industrial applications, and are capable of providing excellent EMI suppression. Additionally, they are durable, reliable, and feature temperature and voltage resistance. The working principle of the PVC16122 film capacitor is based on the electric field stored on the dielectric material between the two electrodes. It is designed to filter out high frequency noise from signals, eliminating any possible interference.
