Film Capacitors

Capacitors are ubiquitous electrical components found in almost every electrical and electronics circuit. Film capacitors are one type of capacitors among several diverse types, such as electrolytic, ceramic, ceramic disc, and tantalum capacitors, and play an important role in the operation of electrical and electronic circuits. According to their construction, film capacitors can be divided into metallized film capacitors, film-foil capacitors, and paper capacitors. The 170563K630GE is a metallized film capacitor.

What are metallized film capacitors?

Metallized film capacitors are capacitors that are made from a thin dielectric film, such as polypropylene, polycarbonate, or polyester, and covered on one or both sides by a metal film or wire evaporated on the dielectric. This type of construction results in a self-healing effect, which means that any damage due to external impacts or short circuits is unlikely to cause a complete failure. This construction also provides good capacitance stability over a wide range of temperature variations, and the capacitors have a good AC ripple current capability.

170563K630GE Application Field

The 170563K630GE metallized polyester dielectric film capacitor is suitable for applications such as switching power supplies, HID ballasts, inverters for fluorescent lighting, UPS, ballast, and other areas, offering advantages such as high insulation resistance, low dissipation factor, and excellent AC ripple current capability.

170563K630GE Working Principle

The 170563K630GE capacitor works in the same way that any other capacitor does - by storing charge and acting as a voltage source for the circuit. When the capacitor is connected to a circuit, the capacitor charges up with electrons until the voltage across it is equal to the voltage supply. At this point, no more electrons can enter the capacitor, and it is said to be “fully charged.”When the voltage supply is removed from the circuit, the electrons will start to seep out of the capacitor. This process is called “discharge” and is the reverse of the charging process. The time it takes for the capacitor to completely discharge will depend on the circuit in which it is connected and the value of the capacitor’s capacitance.The 170563K630GE capacitor also uses a metallized polymer film as its dielectric, which has several advantages over other capacitors. For instance, metallized polymers have excellent dielectric strength and low dissipation factor, among other properties, making them the ideal choice for most applications.

Conclusion

Metallized film capacitors such as the 170563K630GE are very versatile and can be used for a wide variety of applications. They are ideal for use in switching power supplies, HID ballasts, inverters, and other areas due to their excellent insulation resistance, low dissipation factor, and excellent AC ripple current capability. They are also very energy efficient and have a high level of capacitance stability over a wide range of temperatures.
