Introduction

Aluminum electrolytic capacitors are widely used in many electronic applications. Their characteristics – large capacitance, low equivalent series resistance (ESR) and long life – make them invaluable for power supplies, motor drives, and other applications. In this article, we will discuss the application field and working principle of one specific type of aluminum electrolytic capacitor – EKZH250ELL102MJ25S.

Construction and Principles

The EKZH250ELL102MJ25S is a space-saving, radial-lead aluminum electrolytic capacitor with an organic solvent electrolyte. The construction of the capacitor consists of two aluminum electrodes; a cathode which is an aluminum foil with a powder surface to increase the surface area by surface scoring, and an anode which is an etched aluminum foil. Both electrodes are separated by a dielectric layer composed of an insulating paper soaked in electrolyte. The working principle of the EKZH250ELL102MJ25S is simple. Basically, it works using the same principle as other capacitors. When a voltage is applied between the two electrodes, an electric field is created which causes charges of opposite polarity to accumulate on each electrode. This charge then creates an electric field which prevents further charge from accumulating. Thus, the EKZH250ELL102MJ25S acts as a capacitor and stores energy.

Applications of the EKZH250ELL102MJ25S

The EKZH250ELL102MJ25S is designed for general purpose applications. Since it is a space-saving, radial-lead capacitor, it is ideal for applications where PCB size is a concern. It is commonly used in power supplies, motor drives, braking systems, home appliances, and many other equivalent applications. It can also be used as output capacitors in LED driver circuits, in power factor correction (PFC) circuits, and in high-frequency switching circuits. Due to its large capacitance, low ESR, and long life, it is suitable for applications where high efficiency is needed. For example, it can be used to filter high- frequency noise from power supply output, to reduce the start-up current, and to increase power efficiency in motor drives.

Conclusion

The EKZH250ELL102MJ25S is a space-saving, radial-lead aluminum electrolytic capacitor with organic solvent electrolyte. Its construction consists of two aluminum electrodes separated by a dielectric layer, and it works by creating an electric field which prevents the accumulation of further charge. The EKZH250ELL102MJ25S is designed for general purpose applications, with its large capacitance, low ESR, and long life making it suitable for high efficiency applications such as power supplies, motor drives, braking systems, and home appliances.
