Aluminum Electrolytic Capacitors
Aluminum electrolytic capacitors are electrical components used to store electric charges between a pair of metal plates separated by a dielectric material. They play an important role in the design and implementation of electronic systems.ALS81A125QS025 is an aluminum electrolytic capacitor manufactured by Nichicon. It has a working temperature range of -40°C to 105°C, a capacitance of 1200 microfarads (μF), and an allowable ripple current of 420mA. It is available in a 25v voltage rating, with a 500Hz, 60°C frequency rating. The capacitor\'s dimensions are 20x25mm, and it is RoHS compliant.The application field of ALS81A125QS025 capacitors includes automotive, industrial control, power supplies, and various other fields which require high accuracy electrical components. They provide a stable, reliable source of energy for electronic devices. In addition, the capacitors are designed to provide a long life-span of up to 2000 hours, allowing them to meet the requirements for long-term operation in harsh environments.The working principle of an aluminum electrolytic capacitor is based on the same principles as any other capacitor, which is, the storage of charged particles between two conductors separated by a dielectric material. The aluminums electrolytic capacitors use an anode made of a highly reactive aluminum oxide layer, and a cathode made of thin aluminum foil. When an electric current passes through the capacitor, it causes the aluminum oxide layer to generate an electrochemical reaction, which leads to the formation of an insulating oxide film between the anode and cathode. This oxide film acts as a dielectric, enabling the capacitor to store charge.The ALS81A125QS025 capacitor is unique due to its high accuracy, long life-span, and RoHS compliance, making it a great choice for various applications. Its large capacity of 1200μF makes it great for applications such as power supplies, and its low self-discharge rate makes it suitable for applications requiring stable operation over a long period of time. The capacitor is designed for excellent high frequency ripple current capability, making it ideal for use in automotive and industrial control applications. It is also RoHS compliant, making it an eco-friendly choice for applications in which safety and environmental protection are of utmost importance.In conclusion, the ALS81A125QS025 aluminum electrolytic capacitor is a great choice for applications requiring high accuracy capacitors with long life-span and RoHS compliance. Its large capacitance, low self-discharge rate, and high frequency ripple current capability make it suitable for use in automotive, industrial control, and other applications.
