Film Capacitors

Film capacitors describe a class of capacitors using a film, or several films, as the dielectric. Such capacitors are very stable due to their precisely defined capacitance values and low temperature coefficients. The small size makes them well suited for integration in modern electronic equipment. The materials used for their production are dependant upon the specific application.

The MKP1839433084HQ is a film capacitor designed for motor-applications. It has been developed primarily for use in industrial motors, where high dielectric strength and long life cycles are required. The capacitor utilizes radial-leaded construction that allows for easy mounting onto PCBs, and features all-metal construction for increased durability.

Working Principle

The MKP1839433084HQ is a multi-section bipolar capacitor with two leads, each with two inner plates. One pair of inner plates has a dielectric film between them, and the other pair consists of two metal plates insulated from each other. These four inner plates are connected to the outer casing, forming a circuit for electrical conduction. The film is made from polypropylene and is dielectric material of electrolytic grade. This film forms a capacitor that stores electrical energy.

When current passes through the capacitor, alternating current is converted into direct current, with the capacitance dependent on the physical length of the film. The MKP1839433084HQ has an operating voltage of up to 500V with capacitance values ranging from 1uF to 470uF. This combination results in a decrease in the electrical field around the edge of the capacitor, resulting in improved stability.

Applications

The MKP1839433084HQ is mainly used in motor applications, but its outstanding electrical characteristics also make it suitable for several other applications. Its most important feature is its high insulation resistance, making it an ideal choice for applications such as variable frequency drives, motor start-stop-overload operations, frequency converters, AC generator control, UPS systems, auxiliary power supplies, and other industrial applications where voltage transients are present.

The MKP1839433084HQ is also used in many other applications where a reliable and durable capacitor is needed. It is suited for use in sophisticated circuits, such as computer motherboards and professional audio equipment, where its combination of low ESR, long life, and high capacitance make it ideal for those applications.

Conclusion

The MKP1839433084HQ is a reliable, high-performance capacitor that is suitable for a wide range of applications that require a stable, durable, and long-lasting performance. Its high dielectric strength and temperature stability make it an ideal choice for motor applications, variable frequency drives, AC generator control, and other industrial applications. This capacitor is the perfect choice for those applications where cost and performance are balanced against each other.
