Film Capacitors

Film capacitors are popular electronic components, commonly used as motor starters and decoupling capacitors in radio and television circuits. This article focuses on MKP1841222205M, a film capacitor with application field and working principle.

Applications of MKP1841222205M

MKP1841222205M is a 35mm double round snap–in film capacitor. It features high-temperature, self-healing properties, which makes it ideal for motor starter capacitor applications. This type of components is widely used in electronic equipment such as motors, transformers, switchgears and electric tools.

Working Principle

MKP1841222205M works by charging or discharging itself. By doing this, it can either add energy to the electric circuit or remove energy from it and in the end, control and regulate electrical currents. This type of capacitor is composed of two parallel plates known as ‘Conductive plates’ which are separated by an insulating material known as the ‘Dielectric’. When voltage is applied, the conducting plates acquire opposite charges and thus create what is referred to as the electric field between them. This electric field is what creates the capacitance of the MKP1841222205M capacitor.

Advantages

Thanks to the dielectric, MKP1841222205M has a number of advantages over other electronic components, such as: it is able to store a larger amount of electric energy; it is also able to release its stored energy in quick bursts; it is relatively inexpensive; and it can be used in high frequency applications. Moreover, its snap–in design allows for a quick and easy installation.

Disadvantages

On the other hand, one disadvantage of MKP1841222205M is its relatively low voltage tolerance. Also, as these types of capacitors are sensitive to over-voltage, they usually require a voltage protector to keep them from being damaged by an excessive current.

Conclusion

In conclusion, the MKP1841222205M is an excellent choice for motor start – up capacitor applications. It has a certain degree of weather resistance and high-temperature insulation. It is also able to store a large amount of energy, it is relatively inexpensive and can be used in high frequency applications. Despite its various advantages, it is still recommended to have a voltage protector in order to protect it from being damaged by an excessive current.
