Aluminum Electrolytic Capacitors are an important element in electronics engineering. They are widely used in a variety of applications, from ordinary consumer electronics to complex industrial equipment. In this article, we will explore the field of application and working principle of two popular models of aluminum electrolytic capacitors: ELXV100ELL102MK15S.

Application Field
ELXV100ELL102MK15S aluminum electrolytic capacitors are designed for a wide range of applications. They are mainly used in switching power modules, ac-dc and dc-dc converters, in medical, industrial, safety equipment, and consumer electronics. They are also used in automotive electronics, motion control, and motor drive systems. The capacitors also offer low ESR and high-frequency ripple current values while operating in hard switching circuits.

The ELXV100ELL102MK15S capacitors are available in a wide range of sizes. They come in sizes 1.6x6.0, 1.6x7.5, 2.0x6.0, 2.0x7.5, 2.5x7.5, and 2.5x13.9. They can be mounted on printed circuit boards or through-hole installations. The terminals are also standardized for versatility, allowing for easy integration into different systems.

Working Principle
An aluminum electrolytic capacitor consists of an anode foil, a cathode foil, two electrolytic separators (paper or polypropylene) and an electrolyte. A chemical reaction between the aluminum anode and the electrolyte creates a thin oxide layer on the anode foil which acts as a dielectric layer. When a DC voltage (between the two electrodes) is applied, a positive charge is developed on the anode and a negative charge on the cathode. This forms an electric field between the two electrodes, in which the oxide layer acts as an insulating layer. As the anode and cathode electrodes have different electrical charges, a capacitance is formed, which can store an electrical energy.

The capacitance of ELXV100ELL102MK15S capacitors is determined by their size and electrolyte type. Smaller size capacitors usually have higher capacitance values than larger capacitors. Also, different electrolytes (tantalum, aluminum-polymer, etc.) can provide different capacitance values. These capacitors generally have a wide temperature range, typically -40°C to +105°C.

The ELXV100ELL102MK15S capacitors offer excellent temperature and frequency stability, long life, and low ESR. They have a high voltage rating up to 200 volts and a very high ripple current of 600mA at 50Hz. The self-healing and non-polarity of the capacitors make them an ideal choice for a variety of industrial and consumer applications.

In conclusion, the ELXV100ELL102MK15S aluminum electrolytic capacitors are the perfect choice for a variety of applications. They offer excellent performance and long life and are suitable for a wide range of applications, from consumer electronics to industrial and automotive systems.
