Film Capacitors

QXK2J473JTP Application Field and Working Principle

Film capacitors, also known as film dielectric capacitors, polyester capacitors, film and foil capacitors, plastic film capacitors, or simply film caps, are a type of capacitor that use plastic film as a dielectric. They are created by depositing metal electrodes on thin plastic film, usually polyethylene terephthalate (PET) or polypropylene (PP).In general, film capacitors use an inherent low inductance construction, thanks to their construction and form factor. This makes them advantageous in high-frequency applications, and they have higher frequency response compared to other capacitor types like ceramic, tantalum or electrolytic capacitors. Furthermore, they generally have surge capability which helps protect components from voltage spikes, and have excellent high voltage capability for their form factor - meaning they’re better than electrolytic capacitors for high-voltage applications.Film capacitors also generally have good dielectric absorption abilities, making them a desirable choice if high RF shielding and/or long medium frequency impedance is required. They are also very stable over wide temperature ranges, and have high ripple and surge-current capability compared to other types of capacitors.The QXK2J473JTP film capacitors are a type of film capacitor that is specifically designed for AC switching control circuits, with an operating temperature of -40°C to +105°C. It boasts a capacitance range from 1.0 µF to 47 µF and a voltage rating from 250 VAC/300 VDC to 500 VAC/630 VDC.These film capacitors generally feature a robust construction and are shock and vibration resistant. Additionally, the capacitance value range and small size makes these capacitors suitable for a variety of AC switching control circuits. In terms of the working principle, these capacitors are designed in such a way that they store energy in the form of electric charge between two conductive plates separated by a dielectric layer. The dielectric is placed between the two metal plates to increase the capacitance value and to protect it from any electrical disturbances.Due to their resilient construction, the QXK2J473JTP film capacitors are able to withstand frequent voltage fluctuations, surges and other disturbances. Furthermore, they do not suffer from ageing over time, unlike certain other capacitor types, retaining their rated capacitance value for the lifetime of the device.Overall, film capacitors, particularly the QXK2J473JTP ones, are well-suited for AC switching control circuits and other applications as they are able to provide stable capacitance values, stable current-limiting characteristics, and long lifetime. They are also found in portable medical equipment, radio-frequency identification (RFID) systems, automotive and security systems, and various consumer electronics and power supplies.
