Film Capacitors

Film capacitors are capacitors that use an insulating film as a dielectric. They are used not only to store electric energy and provide voltage protection functions in power supplies, but also in the development of electronic products. Film capacitors have the characteristics of large capacity, high insulation resistance, good self-healing properties, long life and high stability compared with other capacitors.

225MSR100K application field and working principle

225MSR100K is a film capacitor produced by Vishay, which belongs to the development series of MSR film capacitors. It is mainly used in the fields of power electronics, instrumentation, telecommunications, automotive industry, consumer electronics, etc. The main feature of this product is the high capacitance value, low equivalent series resistance, and low other losses characteristic, and uses a polypropylene dielectric film shield.

When the 225MSR100K film capacitor is working, electric current circulates between the electrodes, and charges the dielectric film of the capacitor (polypropylene). That said, the potential difference of the capacitor will increase with the increase of charging current, and when the charging current is removed, the capacitor itself will maintain the potential difference between the two electrodes without electricity. This is the process of charging and discharging of the film capacitor.

The capacitance value of the 225MSR100K film capacitor is related to its capacitance value. It can be seen from the structural characteristics that the capacitance value is determined by the volume of the capacitor body, the area of the electrode, and the thickness of the dielectric layer, and their influence on the capacitance value is related. The larger the area of the electrode and the thinner the dielectric layer, the higher the capacitance value. The dielectric layer should be thin enough to ensure that the capacitor remains in the metallized state.

In addition, the temperature coefficient of 225MSR100K capacitors can also be reduced, the available temperature range can be increased, and two connection leads are available. In applications such as power equipment and automation systems, these features are beneficial for increasing the reliability of design.

Conclusion

In conclusion, the 225MSR100K film capacitor produced by Vishay has high capacitance value, low equivalent series resistance and low other losses characteristic. Its wide range of applications and reliable performance characteristics make it a reliable choice for various applications.
