Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as electrolytic capacitors, are capacitors that use an electrolyte to achieve a larger capacitance per unit volume than other types of capacitors. They are most commonly used in high-voltage, high-current, and low-frequency applications. The ALS81A912NP350 is an aluminum electrolytic capacitor from the LS80A Series by Rubicon Technology. This low profile surface mount capacitor is designed for use in board-level power-supply filtering, audio/video applications, and other high-current and high-frequency applications.

Application Field

The ALS81A912NP350 aluminum electrolytic capacitor is designed to handle high-current applications, such as power supply filtering, audio/video applications, and other high-current and high-frequency applications. This capacitor has a voltage rating of 63V and a capacitance of 100 uF. It has an operating temperature range of -55°C to 105°C and is rated for 105°C/6,000 hours. It has a maximum leakage current of 0.20 µA and a height of just 2.4 mm. The LS80A Series is a general-purpose series with a capacitance range from 6.3 μF to 330 μF. It is designed with an aluminum foil and non-solid electrolyte using aluminum electrolytic technology. The superior ripple current capability and low-ESR make it suitable for switching regulators, as well as high-frequency and high-current applications. It has improved solderability for better performance in reflow soldering for high power applications. It is also RoHS compliant and REACH compliant.

Working Principle

An electrolytic capacitor is a type of capacitor that uses an electrolyte solution to store energy. In an electrolytic capacitor, one of the two plates of the capacitor is made up of an electrolyte solution, while the other is made of a metal foil or paper. When a potential difference is applied across the two plates, the metal plate becomes an anode and the electrolyte plate becomes a cathode. This causes a reaction in the electrolyte solution which produces electrons on the metal plate. The electrolyte solution helps to increase the capacitance of the capacitor by allowing the anode to form a larger surface area for the reaction, thus increasing the capacitance of the capacitor. It also acts as an insulator between the two plates, which decreases the amount of leakage current. The electrolyte also helps to stabilize the voltage across the plates, increasing the reliability of the capacitor. The ALS81A912NP350 aluminum electrolytic capacitor has a low-ESR and can handle high-current applications. It is designed with an aluminum foil and non-solid electrolyte using aluminum electrolytic technology. The superior ripple current capability and low-ESR make it suitable for switching regulators, as well as high-frequency and high-current applications.
