Moreover, they can be found in various consumer electronics, including cell phones, computers and television sets.

The working principle of R79PC1220Z340J film capacitors is based on the principle of capacitance. Capacitance is a property of a device that allows it to store energy by creating an electric field between two conductors. The electric field serves to store and discharge electric charge, creating a charge/discharge cycle. The amount of charge that can be stored is called the capacitance, and it depends on the area of the conductors, the distance between them and the type of conductor.

The way that R79PC1220Z340J capacitors work is that when the capacitors are connected to a circuit, the electric field between the conductors will be established. The electric field allows the capacitors to store and release charge in a cycle. After the charge is released, the electric field will be re-established and the cycle will begin again. This cycle is repeated as long as a source is connected to the capacitors, resulting in the capacitors being able to continuously store and output electric charges.

In conclusion, R79PC1220Z340J film capacitors offer a range of features that make them an excellent choice for applications. With the ability to withstand harsh conditions and long service life, they are suitable for usage in a variety of sectors, such as medical equipment, military communication, industrial and consumer electronics. Furthermore, their working principle, based on capacitance, allows them to store and discharge electric charge in a cycle. As such, R79PC1220Z340J capacitors are well suited for many different applications.
