Film Capacitors

Film capacitors, commonly known as plastic film capacitors are a type of capacitor which utilizes a thin plastic film as its dielectric, which creates a much higher capacity than a standard ceramic capacitor. Because there are no losses due to internal dielectric heating, film capacitors are some of the best performing capacitors available. This makes it an ideal choice for applications requiring high precision and stability.

R82EC2100DQ50K application field and working principle

The R82EC2100DQ50K is a polypropylene film capacitor which, thanks to its robust design, high capacitance, and low cost, is ideal for use in a variety of applications including power supply, medical, and audio applications. The R82EC2100DQ50K features a long life rating of 10,000 hours at 70°C, and a very low ESR of 0.1mΩ. This combination makes it well suited for applications requiring long life performance and high ripple current capability.

The working principle of the R82EC2100DQ50K is the same as any other film capacitor – electricity is stored in a thin dielectric film and released when a charge is applied. The thin film is insulated from the capacitor’s metal plates by a dielectric, which determines the capacitance of the device. As charge is applied to the capacitor, the dielectric film creates a thin electric field between the plates, allowing the electric charge to be stored. When a charge is removed, the stored charge is released.

The most important performance parameters of the R82EC2100DQ50K are its capacitance, rated voltage, rated temperature, and ripple current. Its capacitance of 2.1 microfarads is enough for most general-purpose applications, while its rated voltage of 50 volts is suitable for most applications. The rated temperature of the device is 85°C, and its ripple current rating is 200mArms.
