What are Film Capacitors?

Film capacitors, also known as plastic film capacitors, are a type of electrical components which have three layers: two electrodes and an insulated film. They are passive electronic components which are used to store electrical energy. Film capacitors are commonly used to suppress or smooth out AC-DC signals in electronic circuits, filter or stabilize voltage, power electronic systems, or for motor start-up applications.

R75QN3220AA00K Application Field and Working Principle

The R75QN3220AA00K film capacitor from Murata is a surface-mount, X2-class capacitor. It is available in a 0805 package size with a working capacitance of 0.0022µF ±10% and a working voltage of 250VAC. The R75QN3220AA00K is UL approved and is suitable for most commercial and industrial applications.The working principle of this film capacitor is similar to that of any other film capacitor. It has two metal electrodes that are separated by an insulated dielectric material. When electric current is applied to the electrodes, electric charges of opposite polarities accumulate on each electrode and create an electric field which creates a voltage potential between the electrodes. The dielectric material stores electric energy in the form of an electric field. This electric field can store energy over a wide range of voltages and frequencies. One of the main advantages of film capacitors is the fact that they can store large amounts of energy over a wide range of temperatures, frequencies, and voltages.This particular film capacitor is suitable for applications such as motor start-up, filtering, lower EMI and noise generation, voltage stabilization, and power supplies. It is particularly useful in applications that require high reliability and high temperature tolerance.

Conclusion

The R75QN3220AA00K film capacitor from Murata is a surface-mount X2-class capacitor which is suitable for numerous commercial and industrial applications. It has a capacitance of 0.0022µF ±10% and can withstand a voltage potential up to 250VAC. This capacitor offers excellent reliability, temperature tolerance, power storage, and noise reduction, making it suitable for a wide range of applications.
