Film capacitors, identified by the part number MKP385436250JPM4T0, are widely employed in AC and lighting circuits. They are widely used for applications such as power supply filtering, AC blocking, timing, and surge protection. This article will discuss the application field and working principle of these capacitors.

The MKP385436250JPM4T0 capacitors use metallized polyester film as the dielectric material, which is relatively lightweight and can handle voltages up to 630V. The capacitor structure is composed of two metal foil electrodes separated by the film dielectric. In addition, the capacitance values range from 0.022µF to 0.100µF, and the maximum ripple current is 10A.

The capacitors can be used in a variety of AC applications, including power supplies, air conditioning, lighting, computer components, and household appliances. They are also used to provide a degree of stability to low-frequency power supply circuits, and to minimize electrical noise generated in AC circuits, thus increasing system accuracy and efficiency.

The working principle of the film capacitor is simple. When a voltage is applied to the capacitor electrodes, an electric field is created in the dielectric material that stores an electrical charge. The amount of charge stored is proportional to the applied voltage, and the maximum allowable voltage is limited by the dielectric breakdown strength of the capacitor material.

The dielectric strength of the MKP385436250JPM4T0 capacitor is greater than 2kV/mm, which is sufficient for many AC applications. The operating temperature range is -40°C to +125°C, and the capacitors are self-healing, meaning that electrical charge is dissipated as a faint spark when the dielectric breaks down. This protective feature ensures that the capacitors will not be damaged by high voltages.

In conclusion, film capacitors manufactured with the MKP385436250JPM4T0 part number are widely used in AC applications such as power supplies, air conditioning, and lighting circuits. The capacitors are self-healing and have a dielectric breakdown strength greater than 2kV/mm, allowing them to withstand a wide range of voltages. This makes them a reliable and cost-effective solution for many AC power supply applications.
