DME4S56K-F

Application Field

The DME4S56K-F is suitable for use in sensitive power supplies, low ripple noise level protection, mains filtering and motor start and run applications. It also offers excellent performance in power filter and energy storage applications. It is highly efficient at reducing voltage ripple caused by switching power supplies, motor drives and other applications that require a consistent voltage supply, eliminating the need for multiple components. Additionally, it is used in signal processing, providing low-noise applications such as handheld medical devices and communications systems. Its excellent charge and discharge capability also make it a suitable choice for various power systems, such as DC and AC motor drives, variable speed drive systems, UPS, and Lithium-ion battery management systems.

Working Principle

The DME4S56K-F is a non-polarized, high-quality plastic film capacitor. It is manufactured using polypropylene film, and its dielectric material allows for a higher break-down strength and lower dissipation factor compared to other plastic materials. Its unique construction consists of two electrodes, two dielectric layers, and a spacer to hold the electrodes in place. The two electrodes are linked together to form a single electrical node, and when an electrical current passes through the electrodes, the dielectric material is able to store the resulting energy. The capacitance of the DME4S56K-F is determined by the distance between the two electrodes multiplied by the applied voltage.

The DME4S56K-F is designed to have a low ESR (Equivalent Series Resistance) compared to other types of capacitors. This ensures that the capacitor is able to deliver maximum current without any significant changes to its capacitance. This also ensures that the internal inductance of the DME4S56K-F is minimized, providing more consistent performance in applications that require a constant current supply. Furthermore, the DME4S56K-F has a relatively high self-healing process, which allows it to safely store electrical energy without any significant degradation in its performance.
