Aluminum electrolytic capacitors are any type of capacitor that uses an electrolyte to store charge. The ESH476M100AH9AA is a large aluminum electrolytic capacitor that is typically used for various electronic applications. In this article, we will look at the application field and working principle of this capacitor.

The ESH476M100AH9AA is a radial, can-style aluminum electrolytic capacitor with a 100V rating, a capacitance of 470µF and a 5mm diameter. It is non-polarized, and it has an operating temperature range of -40°C to +85°C. The capacitor uses a conductive aluminum oxide layer which is formed on the anode when polarized in order to achieve its high capacitance.

This capacitor finds its application in various electronic devices that require a large capacitance and low ESR. Common applications include automotive electronics, audio/video equipment, power supplies, and internet of things (IoT) devices. The device is also used in applications where noise and ripple suppression is needed in order to reduce interference.

The working principle of the ESH476M100AH9AA is that it relies on the capacitance generated between a conductive aluminum oxide layer and its adjacent electrolyte. The electrolyte serves as a dielectric medium between the aluminum oxide and its adjacent plate, while the aluminum oxide is polarized and acts as the anode of the capacitor. A small space exists between the two electrodes which creates an electric field. When a voltage is applied to the capacitor, ions from the electrolyte migrate to the aluminum oxide layer and create a positive charge which polarizes the oxide layer. This, in turn, creates a current and a capacitance.

The aluminum oxide layer acts as the main dielectric medium, while the electrolyte acts as a secondary dielectric. This combination creates a very stable and dependable capacitor with a very low leakage current. The device is also very resistant to temperature fluctuations and has a long expected lifetime.

To sum up, the ESH476M100AH9AA is an aluminum electrolytic capacitor that finds its application in various electronic devices and circuits. It is non-polarized, has a capacitance of 470µF, a voltage rating of 100V, and a 5mm diameter. The capacitor uses a combination of aluminum oxide and electrolyte to create a stable and dependable capacitor with a low leakage current. Thanks to the high capacitance and low ESR, it is well-suited for use in applications that require noise and ripple suppression and helps ensure a more reliable connection between components.
