Film capacitors are electrostatic storage devices that use a film material as a dielectric. They provide higher capacitance per volume than other types of capacitors and offer excellent temperature stability, wide range of biasing options and long life span. The R413F1220CK00M is an example of such type of capacitors.

The R413F1220CK00M is a film capacitor, with a temperature range of -54°C to +125°C, and a rated voltage of 1220V. The capacitor comprises a plastic body filled with a dielectric film (such as polypropylene or polyester) and is then encased within an aluminum canister.The film capacitor is coated with both aluminum electrodes in a co-planar arrangement to ensure an even and low-resistance connection between the capacitance elements with one side in the form of a metallized film. The central element is carried above and attractively separate from the ground plane the enclosed element by an air gap. This provides the ideal configuration for a capacitor that can tolerate high-temperature and high-voltage.

The R413F1220CK00M is designed for use in a variety of circuits and applications, such as power supply and LED lighting and driving motors. Its long lifespan and stability make it suitable for long-term high-reliability applications. Furthermore, it can be used as a filter in power supply lines to reduce noise and ripple and improve the signal integrity of the circuits. It can also be used in frequency-adjustable circuits, such as DC-DC converters where it stores energy at higher frequencies. Additionally, the capacitor can be used in audio applications, where it filters distortions and hums.

The R413F1220CK00M can also be used in automotive applications due to its high heat tolerance and its ability to quickly recover from transient overloads. It is commonly used in vehicles to reduce electrical noise and ripple produced by the vehicles’ alternators, engine crankshafts, and starter motor. It also filters noise caused by headlights, turn signals, and other lighting systems. By using the R413F1220CK00M, these systems can operate efficiently even at high temperatures.

The working principle of the R413F1220CK00M is based on the physical properties of the dielectric material. When a voltage is applied across the two electrodes of the film capacitor, the material between them becomes polarized. This phenomenon, called dielectric polarization, results in an electrical field that is stronger than the one produced between the plates of an electrolytic capacitor. The electric field in a film capacitor is therefore much higher than in an electrolytic capacitor, resulting in a much higher capacitance for the same volume. In addition, the leakage current of film capacitor is lower than that of an electrolytic capacitor, allowing for prolonged storage times at higher temperatures.

Overall, the R413F1220CK00M is an ideal choice for a variety of applications. Its temperature tolerance range and long lifespan make it suitable for high-reliability high-temperature applications, while its low leakage current and high capacitance per volume make it ideal for filter and energy-storage applications. Its application fields and working principle make it an attractive choice for a range of applications, both in consumer and industrial devices.
