Film capacitors are an important series of capacitors in the various capacitor products, and are widely used in various fields of electrical and electronic technology because of their small size, high stability, reliability, safety and other advantages. The MKP1840351405 is one of the film capacitors. This product has excellent properties such as small size and high dielectric strength, so it is widely used in many fields.

MKP1840351405 application field and working principle

The MKP1840351405 is a polypropylene film capacitor with a capacitance value of 0.015uF. It is suitable for working at a frequency of less than 1KHz and an ambient humidity of less than 45%. Because of its good insulation performance, it can be used in high-frequency switching power supplies, car audio systems, and various electronic circuits. Its use voltage is 500VAC, and its insulation resistance is more than 5000MΩ, which can bring more secure protection for electronic products.

The MKP1840351405 film capacitor is mainly composed of three parts: the film, the electrode and the housing. The film cover made of polypropylene is the main component of the film capacitor, and its role is mainly to separate the two electrodes, forming the dielectric of the capacitor. The materials of the electrodes are generally aluminum foil and copper foil, among which aluminum foil is commonly used. The housing is used for general gathering, and is also a protective measure for the sealing of the capacitor, so that it can better resist dust, pollutants and vibrations.

In addition, the working principle of the MKP1840351405 film capacitor is based on the basic physical principles of capacitance.Under the action of an external voltage, charges have been accumulated on the two electrodes on the film. The two kinds of electric charges of the same property repel each other, forming an electrostatic field in the capacitor. This electrostatic field helps the capacitor to store electrical energy, and the stored energy can be released when a current passes through the capacitor.

In conclusion, the MKP1840351405 film capacitor is widely used in fields such as switching power supplies and car audio systems. Its components are mainly polypropylene film, aluminum foil and copper foil, and its work principle is based on the physical principles of capacitance. In order to better protect the capacitor and its surrounding environment, the capacitor needs to be sealed with a housing and can work normally at a temperature of -40 C to +85 C.
