MKP1848635454P5

Film capacitors, often referred to as electronic capacitors, are a type of capacitor that use thin layers or films of insulating material as the dielectric medium. Unlike electrolytic capacitors, film capacitors offer a wide operating temperature range and stable capacitance over long periods of time. They are available in a variety of styles, shapes and sizes and can provide higher levels of capacitance in a given volume compared to other capacitor technologies such as ceramic. The MKP1848635454P5 is a film capacitor designed for motor frequency-conversion applications and offers high reliability and a long life of at least 100,000 hours even under extreme conditions.

The MKP1848635454P5 is a snap-in (or bolt-in) type film capacitor with an epoxy resin encapsulation for improved durability and reliability. It features a built-in EMI filter that reduces electrical noise when connected to an AC power source. The capacitor has a rated voltage of 450V and a rated capacity of 200μF. The maximum temperature range for the MKP1848635454P5 is between -25°C and 85°C.

The primary application field for the MKP1848635454P5 is motor frequency conversion. Induction motors are widely used in industrial applications and frequency conversion technology is used to change the speed of the motor and increase the efficiency of the system. A frequency converter includes an AC/DC converter (rectifier), an intermediate power DC/DC converter (inverter) and a power adjusting circuit. The MKP1848635454P5 capacitor is used in the inverter circuit in order to filter out EMI and reduce the harmonic distortion created from the frequency conversion process.

The working principle of the MKP1848635454P5 is based on the principle of capacitance and the fact that the dielectric material can store electrical energy as an electric field. The capacitor is composed of two metal plates with a thin dielectric layer between them. When a voltage is applied to the two plates, the negative charge on the one plate attracts the positive charge on the other plate, creating an electric field between the two plates. This electric field stores energy while the current flows through the capacitor. The capacitor\'s capacitance is the ratio of the stored electric charge and the voltage applied and is measured in Farads.

The MKP1848635454P5 film capacitor has excellent electrical performance properties due to the high quality dielectric material used in its construction. Its capacitance remains stable over long periods of time due to the dielectric material\'s low dielectric losses. It is also resistant to temperature changes, making it an ideal choice for applications operating in extreme temperatures. Additionally, it has a low ESR (Equivalent Series Resistance) which results in high efficiency with minimal heat dissipation. Its long life, high reliability, and EMI suppression capability make it an ideal choice for frequency conversion applications.
