Film Capacitors are the most common type of capacitors in the market. They are greatly utilized in various electronic components in consumer electronics and industrial applications. In order to meet the requirements of different applications, the structure and properties of film capacitors can be tailored to meet the specific requirements of the application. The C878BF34250SA4J is a capacitor manufactured by WIMA and is specifically designed for use in consumer electronics and in various industrial applications.

Applications

The C878BF34250SA4J is suitable for various applications such as AC motor controls, AC/DC power converters, inverters,and other industrial applications. It can also be used in various consumer electronics devices, including television, radio, audio/audio visual equipment, and digital cameras.In addition, this capacitor is also used in medical applications, such as in defibrillators and implantable pacemakers.

Structure and Features

The C878BF34250SA4J has a diameter of 8mm and is made up of two pieces of metal film rolled together to create a cylindrical shape. Each piece of film has an electrodeposited layer of a dielectric material such as polypropylene. The layers are stacked together, with the two layers connected by an electrode and held together by an insulating sleeve. This allows the capacitor to provide a high capacitance in a small package.The unique construction of the C878BF34250SA4J allows it to have a low equivalent series resistance (ESR). This means that it can provide better power supply for devices with high power demand. The low ESR also reduces the self-heating of the capacitor, which increases its reliability.

Working Principle

The C878BF34250SA4J works on a similar principle as other capacitor types. It stores electrical energy by trapping electric charge between the two metal films. When a voltage difference is applied to the capacitor, the electric charges are attracted to the other side of the capacitor and move back and forth between the two layers. This creates an electrical current or charge which is stored in the capacitor. The stored electrical energy in the capacitor is released back to the circuit when the capacitor is disconnected from the circuit.

Conclusion

The C878BF34250SA4J is a high-performance film capacitor suitable for a variety of consumer and industrial applications. It offers a low equivalent series resistance, allowing for higher power transfer and reduced self-heating. Its unique construction also provides a high capacitance in a small package, making it a great choice for applications demanding a lot of energy storage in a small form factor.
