Film Capacitors

Film capacitors, or film dielectric capacitors, are capacitors whose base materials are polymer films. This type of capacitor offers very good electrical performance in terms of parameters such as maximum rated voltage, working voltage, tolerance to the DC bias, breakdown voltage and insulation resistance. In addition to these properties, film capacitors boast long service life, compact size and high stability.

The C878BF24200AA4J film capacitor is a great example of this type of capacitor. This device offers a maximum rated voltage of 800 V, a working voltage of 700 V, a tolerance to the DC bias of 4%, a breakdown voltage of 90 V, and an insulation resistance of 10 MO. It is able to safely and reliably handle high voltage applications, and is suitable for use in electric motors, compressors, and air conditioners.

Working Principle

The working principle of film capacitors is based on the design of parallel electrodes which are separated by a film dielectric material. The dielectric material is usually a base film such as polyethylene terephthalate (PET), polycarbonate (PC), or polypropylene (PP). This type of design provides reduced leakage current and a very low dielectric absorption factor. As such, these capacitors are more reliable, efficient, and durable compared to their counterparts.

Regarding the C878BF24200AA4J device specifically, the film material is specifically designed for high-voltage applications and provides a maximum voltage rating of 800V. The working voltage of 700V ensures that the device can function properly in systems with higher voltages. Furthermore, the tolerance to the DC bias, breakdown voltage, and insulation resistance offered by the device are all equal to or better than those offered by similar components.

Application Field

Film capacitors are highly versatile components and are used in various applications such as motor starters, energy meters, power factor correction, and frequency inverters. The C878BF24200AA4J capacitor can be used in applications where a high degree of accuracy and reliability is required. It is often used in motor starters where it helps regulate and reduce currents as well as in energy meters, where it forms part of the metering circuit. In addition, the device can also be used in power factor correction systems, where it helps in the prevention of electrical sags and surges.

Film capacitors such as the C878BF24200AA4J are also widely used in frequency inverters. These devices are commonly used in applications such as electric train control systems, elevators, and home appliance control systems. The high tolerance to the DC bias, breakdown voltage, and insulation resistance offered by this device make it an excellent choice for such applications.

In conclusion, the C878BF24200AA4J film capacitor is an excellent example of a highly reliable and robust device that offers high levels of accuracy and reliability. Its high maximum rated voltage and wide range of applications makes it a suitable choice for a variety of high voltage applications.
