Introduction to ALS71A244NS063 Aluminum Electrolytic Capacitor

Aluminum electrolytic capacitors are a type of capacitor that combines aluminum foil and a conducting electrolyte to form a total of two electrodes. They are typically used for high frequency filter energy storage, blocking and decoupling due to their high capacity and wide frequency range. The ALS71A244NS063 in particular is a surface mount aluminum electrolytic capacitor manufactured by TDK.

Application Field

The ALS71A244NS063 can be used in a variety of electronic components. It is a popular choice for discrete applications such as audio equipment, switch-mode power supplies, motor drives, and electric pumps. Additionally, these capacitors can be used in larger, long-term circuit design such as voltage regulators, solar inverters, car charging stations, and other energy conversion products. The ALS71A244NS063 meets the requirements of low-impedance, low-loss, and low-noise applications.

Product Features and Specifications

The ALS71A244NS063 comes in a small 0805 package, providing a high capacitance in a small volume. Additionally, it offers distinct features such as low ESR (Equivalent Series Resistance) and ESL (Equivalent Series Inductance) as well as high ripple current ratings. This product has a rated voltage of 4V and temperature range of -40 to +105 degrees Celsius, making it well-suited for both low and high temperatures. Typical capacitance values range from 10uF to 470uF.

Working Principle

The working principle of an aluminum electrolytic capacitor is based on Faraday’s law of electrolysis. This law states that whenever electrical current passes through a conductor, its surface charge will be reduced. In an aluminum electrolytic capacitor, an anode (positively charged electrode) and a cathode (negatively charged electrode) are connected to a conductive electrolyte, with a dielectric material like aluminum oxide film sandwiched between them. As electrical current passes through the capacitor, a thin film of oxide is formed on the aluminum foil, reducing its surface charge and thus increasing its capacitance. The structure also helps to reduce the amount of inductance in the capacitor, providing higher frequency characteristics.

Conclusion

The ALS71A244NS063 from TDK is a surface mount aluminum electrolytic capacitor that is ideal for applications requiring high-frequency characteristics. It comes in a small 0805 package offering high capacitance for its size and low ESR, ESL, and ripple current ratings. The working principle of this product is based on Faraday\'s law of electrolysis and provides a high level of energy storage and blocking capabilities. With its wide temperature range of -40 to +105 degrees Celsius, the ALS71A244NS063 is suitable for both low and high temperature applications.
