Film capacitors are a type of capacitor that possess a significant advantage over other types of non-polarized capacitors: high energy density. As such, these components can be used where high capacitance levels and high energy storage capabilities are required. This is especially important in applications that involve audio and video switching and filtering, power supplies, clock oscillators, and control systems.
QXK2J684JTP Application Field and Working Principle
QXK2J684JTP is a metallized polyester film capacitor specifically designed for power supply and power line applications. The combination of a small profile and high operating voltage makes this type of film capacitor particularly suitable for those applications requiring high-efficiency performance. Its working principle is based on the fact that by placing two conductive elelctrodes on a polyester film (commonly referred to as the dielectric), an electric field is created which induces a charge to flow between the two conductors. The dielectric material determines the level of capacitance of the device, and its construction affects the level of dissipation factor (DF) which must be low for superior performance.
The QXK2J684JTP’s film is a polyester film that is metallized with aluminum. This design greatly increases the energy density of the device, as the aluminum layer is thinner than is possible for an electrolytic capacitor. Additionally, this design also provides excellent temperature stability. When using metallized type capacitors, it should be noted that they are non-polarized and they only require a two-wire connection for operation.
This type of capacitor is ideal for high energy applications such as power supplies, DC-DC converters, switching power supplies, high-performance audio/video equipment, and other high-frequency equipment. The QXK2J684JTP is specifically designed for power line applications and is especially suitable for those applications requiring high-efficiency performance. The small profile and high operating voltage of this device make it ideal for high energy/high-frequency applications.
In conclusion, the QXK2J684JTP is a polyester capacitor that is specifically designed for power supply and power line applications. It has a smaller profile and higher operating voltage than conventional capacitors. Additionally, its metallized construction gives it a higher energy density, excellent temperature stability, and non-polar operation. This makes it ideal for power supply, DC-DC converter, switching power supply, and other high energy/high frequency applications.
