URY2G100MHD

Aluminum electrolytic capacitors are one of the most commonly used passive components in modern electronics. The URY2G100MHD is a type of aluminum electrolytic capacitor that boasts a high capacitance and low ESR (Equivalent Series Resistance). It is designed for use in conditions from -55°C to +105°C, making it suitable for a wide range of applications.

Applications

The URY2G100MHD is ideal for use in many types of electronic circuits, such as digital and analog electronics, automotive and industrial electronics, communication circuits, and more. It is also used in power supply circuits, for example, in circuits with a high switching frequency and power consumption. It is also suitable for use in high-energy and high-efficiency power supplies for consumer and computer applications. In addition, due to its high capacitance and low ESR, it is increasingly adopted in the field of automotive onboard charging systems and power steering systems, as well as in solar panels.

Working Principle

An aluminum electrolytic capacitor consists of two electrodes separated by a dielectric layer of aluminum oxide. The electrodes are typically aluminum foil, while the dielectric layer is composed of an oxide that is grown in situ. As a voltage is applied, the oxide layer becomes thinner and its resistance decreases, creating a situation whereby electrons or current flow freely from one electrode to the other. The higher the voltage applied, the higher the capacitance value of the capacitor.

As with most other types of capacitors, the URY2G100MHD has a limited life span, as its capacitance slowly decreases over time. This is due to the gradual break down of the oxide layer, which is a consequence of the chemical reactions taking place between the electrodes, the electrolyte, and the oxide layer. It is important to take these factors into consideration when designing and implementing circuits with aluminum electrolytic capacitors.
