Film capacitors, also known as plastic film capacitors or polyester film capacitors, are widespread in the market. Among them, F863DS105K310Z—a miniature aluminum-cased, 4-terminal, axial-leaded, cylindrical film capacitor, is one of the most popular products. This article discusses the application field and the working principle of F863DS105K310Z.

The most outstanding feature of film capacitors lies in their small volume, high capacitance, low dissipation factor, low leakage current, and high resistance to voltage, temperature and humidity. Thus, they can be applied in wide areas, especially suitable for applications with higher requirement on electrical properties, such as hi-fi audio, radio communication, computer peripheral equipments, electronic testing instruments and the electronic products for the military. Specifically, F863DS105K310Z can provide stable operation even in a wide temperature range from -55℃ to +125℃(-67℉ to +257℉). Therefore, it is an ideal component to reduce the size of circuit and to ensure excellent electrical performance of the system.

The detailed working principle of F863DS105K310Z can be explained as following. The capacitor has two steel plates with a film dielectric between them. When the plates connected to a constant DC voltage source, electric charges will accumulate on the surface of steel plates and form an electric field with the dielectric material between them. The strength of the electric field depends on the voltage applied to it and is proportional to the charge accumulated. This effect is referred to as “capacitance”, measured in Farad. The capacitance of F863DS105K310Z is usually between 0.01μF to 0.1μF. Moreover, the film capacitor can maintain constant capacitance in a wide frequency range and it can be used to act as a medium for coupling signals, decoupling noise, AC blocking, and RF bypassing.

The combined effect of miniature size, high capacitance, low loss and excellent reliability makes F863DS105K310Z is a great choice for designers to solve their efficient design challenges in many fields. Therefore, it is one of the most popular products of film capacitors in the industry.
