Film capacitors are a type of capacitor made from materials like polyester, polycarbonate, polypropylene, polystyrene and polyphenylene sulfide polymers, as well as combinations of some of these materials. Film capacitors are highly reliable, offer low inherent noise and exhibit excellent aging characteristics in harsh environments. The R75RI2150DQ30J is a polymeric electrical film capacitor of the highest quality. It has been built with many excellent features, making it suitable to a wide range of applications.

Applications

The R75RI2150DQ30J capacitor is most often used in the smoothing and filtering of power supply rails. It can be used in high performance railway systems, aerospace systems and in high frequency power inverters. It can also be used as a buffer for LED drivers, as an AC filter for motor and machine control systems and as a power supply filter for military communications equipment. This capacitor is capable of being used in extreme conditions, making it ideal for automotive and off-road high reliability applications.

Working Principle

The R75RI2150DQ30J capacitor stores electrical energy by forming an electrical field between two flat, conductive metal plates. The metal plates are separated by a dielectric material, in this case, a special polymer film. The capacitor gathers, accumulates and stores an electrical charge on the metal plates when charged. When the capacitor is discharged, a momentary current flows between the metal plates, which can be used to supply electrical power to an electrical circuit.

The working of the R75RI2150DQ30J capacitor is based on the principle of electrostatic induction, where electrical charges and charges corresponding to the opposite sign exist simultaneously on two plates. This creates a circular magnetic field with a wide coil making the entire capacitor behave as an inductor. A key feature of the capacitor is that it is a nonlinear component, which means that the current does not remain linear over the life of the capacitor.

The R75RI2150DQ30J capacitor can withstand extremely high temperatures, up to 200°C, making it suitable for a variety of applications, and it can also handle high frequency operation. This makes the capacitor very suitable applications in harsh industrial or automotive environments such as trackside infrastructure or passenger vehicles. It is also ideal for pulse operation, where the high dV/dt capability comes into play.

Conclusion

The R75RI2150DQ30J capacitor is a highly reliable and robust component, designed for use in a variety of applications. It is capable of withstanding high temperatures and frequency operation, making it well-suited for operation in extreme conditions. The capacitor utilizes the principle of electrostatic induction, where it stores electrical energy by forming an electrical field between two conductive metal plates. It is suitable for use in high-performance railway systems, aerospace systems, high frequency power inverters and automotive applications. The R75RI2150DQ30J capacitor is a reliable and versatile component that is suitable for a range of applications.
