Film capacitors, which are also known as polyester capacitors, are used to store electrical energy and protect sensitive electronic circuits. They are generally composed of a thin plastic film that is layered with two metal plates. These capacitors are preferred for their low leakage, high stability and high capacitance values. They are also highly reliable, have a long life expectancy, and are lightweight and compact.

The product code QXK2J223JTP7FJ is a film capacitor from Panasonic which is part of their EG and EK series. It is designed for applications such as TV sets, home theatre systems, and multimedia systems. The product is an aluminum electrolytic capacitive element that is packaged in an EIAJ case with an insulated terminal. This film capacitor can withstand voltages of up to 1000VAC and has a wide capacitance range from 0.00100μF to 10 000μF. In addition, it has a temperature rating of -40°C to 85°C and has a long shelf life of up to 6 years.

The working principle of a film capacitor is based on the principle of capacitance which states that when two parallel plates are separated by a non-conducting dielectric material, such as a thin plastic film, an electric field will be created by the charges on each plate. The electric field will cause a potential difference between the two plates and this potential difference will cause a current to flow between them. The current will cause a charge to accumulate on each plate, and the magnitude of the charge is directly related to the capacitance of the system. This capacitance is measured in farads and it determines the amount of electric energy the capacitor can store.

Film capacitors have a wide range of applications and are used for power supplies, filter circuits, high-frequency circuits, constant-voltage supplies, line-bypass capacitors, and smoothing circuits. They are also used for start-up and hold applications in radio frequency systems, for blocking high voltages in high power applications, and for DC-link applications. Film capacitors are very popular in today’s electronics due to their low leakage, high stability, long-term reliability, and their low cost.

In conclusion, the QXK2J223JTP7FJ film capacitor from Panasonic is an aluminum electrolytic capacitive element that is packaged in an EIAJ case with an insulated terminal. It has a wide capacitance range, excellent temperature characteristics, and a long shelf life. Film capacitors have a wide range of applications, from power supplies to high-frequency circuits to start-up and hold applications in radio frequency systems. The working principle of a film capacitor is based on the principle of capacitance which states that when two parallel plates are separated by a dielectric material, an electric field will be created and the current will cause a charge to accumulate on each plate depending on the capacitance of the system.
