Film capacitors, also known as plastic film capacitors, are passive electronic components composed of a single layer or multiple layers of plastic film medium and upright aluminum foil electrodes. The B81141C1104K000 is one such film capacitor.

B81141C1104K000 Application Fields

The B81141C1104K000 is a DC-link type capacitor with high capacity for a film capacitor. It is suitable for applications with a rated voltage of 400V and capacitance of 1000μF. It can be used in various fields including electric energy storage, DC power transmission and distribution, frequency conversion and soft start, solar power systems and so on.

The B81141C1104K000 has excellent self-healing performance, which means that when it is subjected to extreme voltage conditions and strikes, it can still restore the normal electric charge to the capacitor. This makes it suitable for all kinds of arc-sensitive devices, such as variable frequency drives and motor controls, wind, solar and hybrid energy storage systems, and the like.

B81141C1104K000 Working Principle

The working principle of the B81141C1104K000 is very simple. When the electric charges on the two ends of the film capacitor are offset, an electric field will be formed between them and dielectric medium, which is the plastic film itself. This electric field will accumulate electric charges on both sides of the diaphragm capacitor, and the capacitance is generated by the electric field.

The electric field in the film capacitor will be strengthened or weakened by the dielectric performance and the distance between the electrode and dielectric medium. When the electric field is weakened to a certain extent, the electric charges on both sides of the diaphragm capacitor will be offset and the electric charge will stop. This ensures that the maximum electric field is not exceeded to protect the safety of the capacitor.

Conclusion

The B81141C1104K000 is a film capacitor that can be used in a wide range of fields, including energy storage, DC power transmission and distribution, frequency conversion and soft start, and solar power systems. It has excellent self-healing performance and a maximum working voltage of 400V. The working principle of the B81141C1104K000 is based on the interaction between electric fields and dielectric mediums, which allows for the accumulation and discharge of electric charges on the electrodes.
