Film Capacitors: F339MX232231MD02G0 application field and working principle

What is Film Capacitors? A Film Capacitor or Polyester Capacitor is a type of electrical capacitor that uses a film made of polyethylene terephthalate (also known as PET or Mylar) as the dielectric. Such capacitors are used in many consumer electronics, in fluorescent lamp electronic ballasts, noise filters, etc. Film capacitors are also commonly used in RF applications as they provide a high degree of stability over wide temperature ranges.

It is suitable for cables with high electric fields, high-capacity meters, discharge circuits, computer switch box, etc. Besides, due to its excellent damping characteristics, it can be also used in vibration damping. It is a high-precision type which can be used in miniaturized electronic systems.

Working Principle

The F339MX232231MD02G0 is a type of unipolar capacitor. This means that its consists of two conducting plates, one supplied with a positive charge and the other with a negative charge. These plates are separated by a non-conducting material, which acts as an insulator and forms the dielectric material of the capacitor. When electrical current flows through the capacitor, it creates an electric field, which helps to store the energy stored in the capacitor.

The capacitance of the F339MX232231MD02G0 capacitor depends on the thickness of the non-conducting material, as well as the area of the two conducting plates. Generally, the capacitance of the capacitor increases with decreasing thickness and area of the conducting plates. The capacitance of the F339MX232231MD02G0 is approximately 0.0022 μF, which is considerably higher than other similar-sized capacitors.

The F339MX232231MD02G0 is temperature resistant and can operate at temperatures up to +105℃. It also offers excellent performances in terms of capacitance, voltage and frequency. Its rated voltage is 250VAC and the maximum capacitance deviation is 5%. The frequency range extends up to 500 MHz. Furthermore, the F339MX232231MD02G0 has superior insulation resistance, on which it achieves a value above 1 GΩ·μF.

In conclusion, the F339MX232231MD02G0 is a type of polyester film capacitor ideal for high-frequency applications. It is small in size with low EMI and stability characteristics. This makes it suitable for embedded systems and cables with high electric fields.
