Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is an electrical component that stores a charge and can be found in almost all electronic devices. They are typically one of the most common types of capacitors seen in electric and electronic circuits. Aluminum electrolytic capacitors are used for various purposes, including in the filtering of power supplies, in energy storage applications, and in signal coupling and decoupling circuits. This article will explore in detail the application field and working principle of aluminum electrolytic capacitors, in particular the 515D475M063JA8PE3 model.

Application Field and Working Principle

Aluminum electrolytic capacitors are found in a wide range of electronic and electrical applications, including power supply filtering circuits and energy storage applications, and in signal coupling and decoupling circuits.In power supply cases, aluminum electrolytic capacitors are used as a store of electrical charge in order to even out large current fluctuations or as a filter to suppress high-frequency interference.In energy storage applications, aluminum electrolytic capacitors are used as a substitute for rechargeable batteries as they can store and maintain a charge for longer than batteries, as well as provide higher energy densities. In coupling and decoupling applications, aluminum electrolytic capacitors are used as devices which can change the characteristics of a signal, allowing for signal distortion before and after amplification. In signal conditioning applications, aluminum electrolytic capacitors are used as a transient protection device for inductive loads.

Aluminum electrolytic capacitors use a combination of an electrolyte and a dielectric to store electrical charges. The electrolyte of an aluminum electrolytic capacitor is formed by two thin layers of aluminum oxide, a dielectric material, typically grown on the surface of two aluminum plates. The aluminum oxide layer acts as a dielectric, preventing the plates from coming into direct contact with each other, but allowing for electrical current to pass between them. This type of electrolytic capacitor has a sealed construction and is filled with an electrochemical fluid known as electrolyte. The electrolyte facilitates the movement of ions between the plates of the capacitor, allowing it to store electrical energy.

The 515D475M063JA8PE3 aluminum electrolytic capacitors, specifically, are mainly used for premium audio applications, as it features very low leakage current and low equivalent series resistance (ESR). It has a surge current capacity of 820％ IRE and capacitance of 47μF, and has a wide operating temperature range of -40 to +105℃. It has an operating voltage of 16V, and a height of just 6.3mm, making it ideal for applications where space is an issue. This model is also specifically designed to reduce stray inductances, and are constructed with the electrolyte sealed between the aluminum "can" electrodes, to especially reduce spikes or radiations.

Aluminum electrolytic capacitors are one of the most dependable and inexpensive types of electronic components available. They have the advantage of a small size and a relatively low cost. They are also relatively easy to manufacture and are often the most reliable kind of capacitors for larger applications. The 515D475M063JA8PE3 aluminum electrolytic capacitors are an especially reliable model, perfect for applications where small size and long life are important criteria.
