Film capacitors, also known as film dielectric capacitors, are electrical components composed of two electrodes that are separated by a metallized plastic film. They are commonly used to store electrical energy in electronic circuits. The QXK2E155KTP7FM is one such film capacitor, and it is used in a variety of applications in electrical and electronic equipment.

The QXK2E155KTP7FM has a voltage rating of 125 VAC, a capacitance of 155 mF, and a rated ripple current of 2.2 A (pp). Its construction includes a non-flexible metallized plastic film dielectric, niobium metal-oxide electrodes, and a phenolic resin encapsulation material. It is designed to provide reliable electrical performance in applications where high capacitance and long-term reliability are required.

The QXK2E155KTP7FM is typically used in applications such as power supplies, DC to DC converters, high-efficiency power circuits, and consumer appliances. In these applications, it is used to store electrical energy and to dampen electrical current spikes. It can also be used in filter circuits to reduce high-frequency noise, and in high-voltage applications such as switch-mode power supplies and motor drivers.

The working principle of the QXK2E155KTP7FM is based on the principle of electrostatics. This principle states that when two electrodes, separated by a dielectric material, are subjected to an electric field, an electrostatic charge will be induced in the dielectric material. This electrostatic charge is then stored in the film capacitor.

When a voltage is applied across the two electrodes of the film capacitor, charge starts to flow in the direction of the electric field. This charge flow will increase until the voltage at both ends of the capacitor is balanced, at which point the capacitance is considered to be fully charged. The capacitance is then discharged when the voltage is removed, and the capacitor is reset to its original state.

The QXK2E155KTP7FM is a durable, high performance film capacitor that is designed for long-term reliability in a variety of electrical and electronic applications. Its robust design ensures that it will provide reliable performance in applications requiring high capacitance levels and long-term reliability.
