Film capacitors, also known as plastic film capacitors, are ubiquitous passive components used in a wide range of applications such as power supplies, communication and automation systems, audio amplifiers and consumer electronics. 890324023011CS is one of the most popular types of film capacitors, and its application field and working principle are as follows.

Application Field

890324023011CS film capacitor is mainly used in high-frequency switch power supply and high-current electrical fields. It is also used in many other applications such as frequency dividers, power dividers, voltage resonators, power-factor improvement apparatus, filters, coupling circuits, and voltage-mode or current-mode motors. Moreover, this type of capacitor can also be used in high efficiency DC/DC converters, electronic ballast, UPS, or resonant circuits, etc.

Working Principle

The working principle of 890324023011CS film capacitor is based on the capacitance produced by two metal foils which are separated by a layer of plastic film, acting as a dielectric, and are electrically isolated from each other. When the capacitor is exposed to an electric field, electric charge will be induced on both metal plates and a charge separation will occur. The amount of electrical charge stored in the capacitor is determined by the capacitance of the capacitor and the voltage across the capacitor. Therefore, when a DC voltage is connected across the capacitor, the capacitance value of the capacitor will increase, and when the DC voltage is removed, the capacitance value of the capacitor will decrease.

Advantages and Disadvantages

The main advantages of 890324023011CS film capacitor are its large surge current capability, high fatigue life, high insulation resistance, and high temperature rating. Moreover, it has a good self-healing behavior, low noise and vibration, low inductance, good heat dissipation, and high reliability. On the other hand, this type of capacitor has some drawbacks, such as its relatively low dielectric strength and high leakage current.

Conclusion

In conclusion, the 890324023011CS film capacitor is a popular type of capacitor which is widely used in high frequency switch power supply and high current electrical fields, as well as many other applications. It has a number of advantages, such as its large surge current capability, high fatigue life, high insulation resistance, and high temperature rating, amongst others. However, it also has some drawbacks such as a low dielectric strength and high leakage current.
