930C6P68K-F

Film capacitors, also known as plastic or dielectric capacitors, are passive components that store energy in the electric field between two or more electrical conductors. They are polarized capacitors with an earlier dielectric used, typically paper, now largely replaced by polyester, polycarbonate, etc. This type of capacitor has a wide range of application fields and is used in a variety of electrical applications, from filter and decoupling circuits to timing and power control. The 930C6P68K-F is an example of a film capacitor used in commercial applications.

Application Field

The 930C6P68K-F film capacitor is a polypropylene film capacitor with a wide capacitance range between 10 and 68000 µF. It is typically used in power supplies, audio-video circuits, consumer electronics and communication equipment. Its applications range from low frequency bypass and coupling applications to high frequency decoupling for signal processing. The 930C6P68K-F is also used in noise filtering, anti-glitch circuit applications and precision AC and DC power supply circuits.

Working Principle

The working principle of a film capacitor is based on the basic capacitance concept. A capacitor can be defined as an electrical component that stores energy in the form of an electric field between two conductive plates. When a voltage is applied across the plates, the field generates an electric current that flows through the capacitor. This current is proportional to the applied voltage and the capacitance. In the case of the 930C6P68K-F, the capacitance range is 10 to 68000 µF and the voltage is 6.3 VDC.

The 930C6P68K-F is a non-polar capacitor, which means it does not have any polarizing electrolytic material between its plates. Its internal construction consists of various layers of polypropylene foil which are sandwiched together. As the voltage increases, the electric field generated between the plates pulls the electrons from one plate to the other and an electric current is created. This current can be used to filter or decouple the power supply for various audio or video applications.

Apart from its large capacitance range, the 930C6P68K-F film capacitor also offers a wide operating temperature range of -40°C to +85°C. This makes it suitable for a variety of operating environments and is certified for electromagnetic compatibility (EMC). It is also UL approved and RoHS compliant.

In conclusion, the 930C6P68K-F film capacitor is a non-polarized capacitor with a wide capacitance range of 10 to 68000 µF, making it suitable for a range of applications. Its wide operating temperature range, EMC certification and UL approval makes it ideal for use in power supplies, audio-video circuits, consumer electronics and communication equipment.
