Film capacitors are a type of capacitor, also known as plastic film capacitors, which are filled or encapsulated with a plastic film. The two main types are polypropylene and polyester. 160393J630G-F is a polyproplyene film capacitor and this article will explain its application and working principle.

Application Field

Polypropylene film capacitors are used for a variety of applications. This includes snubber circuits, pulse shaping, signal and power conditioning. They also have applications in power supplies, power conversion, AC motor speed control and DC motor control.

Due to its excellent characteristic such as stability at high frequencies, 160393J630G-F is designed for use in high frequency circuit applications including AC/DC converter, power cycle control circuits, switches and inverters.

In power amplifying circuits, 160393J630G-F can be used for both coupling and DC blocking. It can also be used to filter low frequency or DC signals, and for wave shaping, low pass filters, audio amplifiers, etc.

Working Principle

Film capacitors are produced by winding two strips of foil which are separated by a plastic film. The foils are made from either aluminium or copper, which are coated with a thin layer of metal oxide to act as a dielectric. This means that an electrical current cannot pass through the capacitor and charge will accumulate on either side of the dielectric.

When an AC (alternating current) voltage is applied across the capacitor, the current will pass through the dielectric rapidly. This results in an electrical current that switches on and off, creating an electromagnetic field which is known as the capacitive reactance.

When the current is switched off, the electric field dissipates and creates a magnetic field around the capacitor. This magnetism causes a current which is the result of the AC voltage.

In DC voltage applications, the electricity is allowed to accumulate on both sides of the dielectric, creating the charge which can be used to power circuits. It is for this reason that DC voltage is referred to as “static electricity” as it does not cause any current.

Conclusion

The 160393J630G-F is a polypropylene film capacitor and is used for a variety of applications. Its excellent characteristic such as stability at high frequencies makes it a great choice for use in high frequency circuit applications, as well as power amplifying circuits. Its working principle is based on winding two strips of foil which are separated by a plastic film, and then applying an alternating or direct current voltage across the capacitor.
