Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors are widely used electronic components used in power circuits. They are non-polarized electrolytic capacitors that store energy in an electric double layer, formed by two thin layers of aluminum oxide and separated by a thin layer of electrolyte. Anode of the capacitor is the aluminum foil with a layer of oxide, Cathode is a very thin wet paperlike strip.

ELH229M025AS4AA is an aluminum electrolytic capacitor that has a capacitance of 56µF with a maximum working voltage of 50V and a wide temperature range of -40 - +85 °C. It has a maximum capacitance tolerance of ±20%. The application field and working principle of this aluminum electrolytic capacitor are further discussed below.

Application Field

ELH229M025AS4AA aluminum electrolytic capacitor is commonly used in various consumer electronics, gaming consoles, computer systems, audio, video and telecommunications industry. It can be used in motor control circuits, filter circuits, and audio systems.

In computer systems, it can be used as bypass capacitors for regulating voltage. In audio systems, it is used to filter out any DC components from the audio signal. In video and telecommunications industry, they can be used as transient voltage suppressors in power supplies and signal protection devices.

Working Principle

The working principle of the ELH229M025AS4AA aluminum electrolytic capacitor is based on the formation of an electric double layer. When an AC voltage is applied to the capacitor, electric charges are stored in the electric double layer formed between the oxide layer and the electrolyte layer. This stored charge can then be used to supply current upon demand.

The capacitor is composed of two metal foil electrodes, an aluminum anode and a cathode. The anode is coated with an oxide layer, which acts as the dielectric layer. The cathode is a paperlike strip that is kept wet with an electrolyte solution. When a voltage is applied to the capacitor, the anode and the cathode become polarized and form an electric double layer.

The stored charge in the electric double layer can then be used to supply current and the capacitor thus acts as a buffer to regulate the flow of current. The ELH229M025AS4AA aluminum electrolytic capacitor also has a wide temperature range of -40 - +85 °C, which makes it suitable for use in harsh environments.
