Film capacitors, also known as plastic film capacitors, are capacitors which use a dielectric film made of polyester, polycarbonate, polypropylene, polyethylene, polyphenylene sulfide, and other plastic films as the dielectric materials between the anode and the electrolytic capacitor. They are widely used in a range of applications, such as AC and DC power filters, signal decoupling, high precision analog circuits, and pulse circuits for medical and automotive applications.

The QAP2E475KRP is a film capacitor from the company Syfer Technology, a leader in the design and manufacture of film capacitors. It is a high reliability, high quality, and cost-effective component, offering extreme high performance and very consistent characteristics. It has a very small form factor and low ESR, making it an ideal solution for many high-performance/high-reliability solutions.

The QAP2E475KRP has a wide operating temperature range of - 55 째C to + 125 째C. Its design includes a polypropylene film dielectric, silver-plated anode and polyethylene Nylon sleeve. Moreover, this film capacitor is RoHS compliant and meets UL 94V-O standard.

In terms of applications and working principle, this film capacitor is mainly used for AC and DC power filters, signal decoupling, high-precision analog circuits, and pulse circuits for medical and automotive applications. So, it is suitable for many of these uses, providing strong and consistent performance in each application.

The principle behind a film capacitor is simple. It consists of two electrodes in the form of metal plates, separated by a dielectric. In the case of the QAP2E475KRP, a thin layer of polypropylene film serves as the dielectric. When the capacitor is connected to a power source, the plates are charged and a charge buildup is created between them.

This difference in charge causes an electric field between the two plates, with the electrons in the dielectric repelling each other, resulting in a stored positive charge on one plate and a stored negative charge on the other. This stored charge is what is known as capacitance and the amount of capacitance will depend on the size and geometry of the plates, as well as the dielectric material used.

The main advantage of a film capacitor is that it has a high capacitance density relative to other types of capacitors. This means that, for the same volume, a film capacitor can store more charge than an electrolytic or ceramic capacitor. Moreover, it is a very low-loss dielectric, meaning it doesn’t dissipate much of the energy stored in it even after prolonged use. It also features very low ESR values, which further contributes to its effectiveness.

The QAP2E475KRP film capacitor from Syfer Technology is a reliable film capacitor that is suitable for many applications in fields such as medical and automotive, offering strong and consistent performance. Its high capacitance density and low ESR values make it a great choice for high-precision analog circuits and pulse circuits, while its small form factor and wide operating temperature range make it an ideal solution in areas where space is at a premium.
