Film capacitors are electrical capacitors typically composed of paper, plastic film, and/or polyester which utilize an insulating film dielectric. An MKP385591025JKP2T0 is an example of a film capacitor whose application field and working principle will be discussed in the following article.

Overview

The MKP385591025JKP2T0 is a plastic film capacitor designed to perform as an interference suppression (EMI) filter, a capacitance extension in parallel circuits, and a damping for high-frequency signals on a circuit board. Due to its style, the MKP385591025JKP2T0 is best utilized on circuit boards with large offsets (a flat surface where components are placed); they are extremely small and the pin spacing does not exceed 1.25 mm.

Advantages

The MKP385591025JKP2T0 offers several advantages: namely, an increased stability of the equivalent series resistance (ESR) due to its low-resistance metallized film material; a decrease of self-resonance frequencies due to its specialized metallized structure; and a low risk of flashover due to the small gap between pin tips of the capacitor. This enables the MKP385591025JKP2T0 to be utilized in high-frequency electronic circuits for stabilizing, frequency filtering, and capacitance extending.

Application Field

The MKP385591025JKP2T0 is designed for use as an interference suppression (EMI) filter, a capacitance extension in parallel circuits, and a damping for high-frequency signals. As an interference suppression capacitor, it is an effective component for filtering out high-frequency noise from incoming power sources, as well as reaching the ability to meet the requirements of both EN55022 or FCC Class B standards. As a capacitance extension in parallel circuits, the MKP385591025JKP2T0\'s extremely small size helps to reduce the rate of self-resonance in the circuit, which can frequently act as a cause of unstable circuit performance. Finally, it can be used as a damping for high-frequency signals on a circuit board, mainly due its highly efficient low-resistance metallized film material.

Working Principle

Like other capacitors, the MKP385591025JKP2T0 works by storing an electrical charge and then releasing it. The current in the capacitor is actually stored in the form of an electric field. This field is created when an electric field, or voltage, is applied across two conductors. When a given voltage level is attained across these two conductors, the electric field will travel across the dielectric material between the two conductors, generating an electrical charge. As this charge accumulates, the current flow between the two conductors increases.

The MKP385591025JKP2T0 also includes an specialized metallized film material, a kind of material which is extremely efficient at conducting electricity. This material further enhances the current flowing through the capacitor, making it even better at storing the electrical charge and releasing it quickly, thereby increasing the speed with which current flows through the capacitor. This in turn makes the MKP385591025JKP2T0 well-suited for use in high-frequency electronic circuits.

Conclusion

An MKP385591025JKP2T0 is an example of a plastic film capacitor typically used in film capacitors. This component\'s application fields include use as an interference suppression (EMI) filter, a capacitance extension in parallel circuits, and a damping for high-frequency signals on a circuit board. Its working principle involves storing an electric field created when a voltage is applied across two conductors, which is further enhanced by its metallized film material. As such, the MKP385591025JKP2T0 is well-suited for use in high-frequency electronic circuits for stabilizing, frequency filtering, and capacitance extending.
