Film capacitors are passive electrical devices consisting of an insulating plastic film sandwiched between two metal plates. They are available in many different form factors and surfaces; for example, B32521C6683J comes in an axial lead, rectangular shape. These capacitors are used in a variety of applications due to their stability, precision, and ability to store electrical energy.

Applications

B32521C6683J capacitors are particularly useful in DC-DC converters, audio applications, LED lighting, and high voltage power supplies due to their beneficial features. The capacitors help to filter out higher frequencies and control the current pulse, making them the ideal choice for these applications. Additionally, the wide range of capacitance allows these capacitors to be used in more specific applications such as snubber circuits, AC line filters, and lighting ballast.

Working Principle

In a film capacitor, the insulating plastic film acts as a dielectric material to store energy. A voltage applied across the capacitor causes charge to accumulate on a layer of the film, creating a field of electric force between the two metal plates. This electrical field then causes an increase in surface charge on the capacitor’s dielectric. This potential difference stored between the plates of the capacitor is stored until the capacitance is discharged to the ground or returned to its original state.

The ability of the capacitor to store energy for a period of time is dependent on its capacitance. The capacitance is a measure of how much potential difference can be stored on a given dielectric. The higher the capacitance, the greater the charge can be stored. In order to achieve the desired capacitance, the insulating plastic film used in film capacitors can be made thicker or thinner to alter the charge storing capacity.

The B32521C6683J capacitors have a temperature coefficient of capacitance (TCC) of -15% per degree Celsius. TCC is the rate at which the capacitance value changes due to a change in temperature. Generally, film capacitors have a steeper TCC compared to other types of capacitors making them ideal for temperature-sensitive applications.

Conclusion

B32521C6683J capacitors are film capacitors that can be used in many different applications due to their beneficial features. They have a wide range of capacitance, good stability, and relatively high temperature coefficient of capacitance, making them ideal for precision control and high voltage applications. The principle behind the capacitor is that a voltage applied across the capacitor causes charge to accumulate on a layer of the film, creating an electrical field between the two metal plates. This field is then able to store energy until it is discharged.
