Film capacitors, sometimes referred to as foil capacitors, are a type of capacitor that use a flexible dielectric material, typically a thin polymer film, to separate the two conducting electrodes.

The QXL2E154KTPT film capacitor is a high-quality aluminum electrolytic capacitor manufactured by the AVX Corporation, with a cylindrical shape and hermetically sealed cases. It has a rated value of 2.2uF, 250V AC/DC and is designed for single-sided connection. In addition, the QXL2E154KTPT capacitor features a low ESR, long stable life and a high operating temperature range of -30C to +85C.

Film capacitors are widely used in various applications due to their make up of a dielectric film for insulation. They are used for storage, decoupling, filtering, power factor correction, energy storage and transmission, and other capacitive electric energy applications. Some examples of the QXL2E154KTPT application field include AC line filtering and DC link capacitors, inverter capacitors, high-voltage DC converter capacitors, and busbar capacitors.

The working principle of any film capacitor is based on the fact that electric charges of the same sign repel each other. Film capacitors consist of two metallic electrodes that are separated by a dielectric insulating film. When a voltage is applied across the two electrodes, it creates an electric field which causes electrons to accumulate near the electrodes, forming an electric charge.

The electric field between the two electrodes causes an electric polarization of the dielectric material which produces a capacitance. This allows the capacitor to store a certain amount of electrical energy which can be released when the voltage across the capacitor is reduced. The capacitance of the QXL2E154KTPT film capacitor is 2.2uF, so the amount of energy it stores is proportional to this value.

The QXL2E154KTPT film capacitor is also known for its excellent performance in electrical applications, such as low ESR and long stable life, due to its hermetically sealed cases which effectively improves the dielectric strength. In addition, this capacitor features a wide operating temperature range of -30C to +85C, so it can be used in high temperature applications.

Overall, the QXL2E154KTPT film capacitor is an excellent choice for applications that require a reliable, high-quality capacitor with a long operating life, excellent performance, and a wide temperature range. It is used in many electrical applications, such as DC and AC line filtering, inverter capacitors, high-voltage DC converter capacitors, and busbar capacitors. The working principle of any film capacitor is based on the electric polarization of the dielectric material, which stores electrical energy that can be released when the voltage is reduced. Moreover, the QXL2E154KTPT\'s hermetically sealed cases improve the dielectric strength of the capacitor, enabling it to perform optimally in a wide range of temperature applications.
