Aluminum electrolytic capacitors are found in a wide array of electrical circuits and systems, from consumer electronics such as radios and televisions to industrial equipment and computers. They come in a vast range of sizes and capabilities, making them a versatile component. The specifics of each capacitor can be found in its code. The code 515D105M100JA8PE3 is an example of such a code and indicates the nature of the capacitor and its performance.

Application Field

Aluminum electrolytic capacitors are used in many applications and can be categorized into two main types: polarizing capacitors and non-polarizing capacitors. Generally, polarizing capacitors are used for their low leakage and low self-discharge current, and non-polarizing capacitors are used for their higher capacitance values and low ripple current capabilities.

The code 515D105M100JA8PE3 is of a non-polarizing type and used for general purpose applications, such as bypassing, decoupling, blocking, signal filtering and time delays. It is designed for an operating temperature of -40°C to 85°C and is rated for 50,000 hours of operation.

In general, aluminum electrolytic capacitors are used in power supplies, audio equipment, robotic systems, medical implants, industrial control systems, and telecom applications.

Working Principle

An aluminum electrolytic capacitor is constructed of two plates that are placed in a liquid electrolyte. One plate is made of aluminum, while the other is made of a conductive material such as tantalum or aluminum oxide. A small amount of current is passed to the plates, causing the electrolyte to break down the oxide layer on the metal plates, forming two thin layers of oxide.

This thin layer of oxide serves as an insulating layer, allowing a charge to build up between the two plates when a voltage is applied. This charge can be stored in the capacitor for a period of time, allowing it to act as an electrical buffer. As current is drawn from the capacitor, the charge between the two plates steadily decreases.

Aluminum electrolytic capacitors have several advantages compared to other types of capacitors, including a high capacitance density, low cost and low instability due to temperature variations. However, they also have some drawbacks, such as having a limited operating temperature range, low reliability and a shorter lifetime.

The capacitor code 515D105M100JA8PE3 indicates this particular aluminum electrolytic capacitor has a capacitance of 105μF, and is rated for up to 100V. It can be used in a wide range of applications, including power supplies, audio equipment, robotic systems, medical implants, industrial control systems, telecom applications, and other general-purpose applications.
