Film capacitors are electronic components of great importance, their mission is to filter, store charge, coupled and divide electric signals, as well as to stabilize voltages and currents. The BN104I0683J model belongs to this type of capacitors, made with film materials. Its most notable features are:

• Very good and stable properties that remain during temperature changes and long-term operations.
• Low losses in the processing of alternating signals.
• Good behavior at high frequencies.

The application field of the BN104I0683J is varied: they can be found in power supplies, transformers, electrical converters, HF filters, among some other applications. It is important to take into account the fact that the value of its capacitance can be affected by the operating temperature, the type of dielectric and the frequency, therefore it is always recommended to check the validation conditions indicated by the manufacturer.

The working principle of film capacitors relies on their dielectric layers. Their construction is composed of multiple layers of metal filament, each of them is called electrode, it is separated by a dielectric material which is usually a polymer. This material establishes an electrical barrier between terminals, which provides the capacitor with its characteristics.

Insulating layers are constructed from dielectric films which are obtained by coating multiple surfaces of thin plastic or paper impregnated with polypropylene. These films can be one or several layers, featuring a thicker thickness compared to the other types of capacitors. This feature provides them with better mechanical tension, as well as lower losses of signals.

Finally, it is important to emphasize that film capacitors are electromechanical devices, it means, they can suffer damage due to vibration, so it is recommended the use of adequate protection when exposed to slightly vibrating environments. The value of the capacitance for models such as BN104I0683J it is measured in Farads, which is a unit of electronic capacity, which defines the capability this model has to store energy under different temperature conditions.
