Aluminum electrolytic capacitors are a common type of capacitor that are widely used in electronic circuits, especially in power supply filtering and decoupling circuits. Its main feature is the use of aluminum foil as the electrode material and electrolyte as the medium. This structure enables aluminum electrolytic capacitors to have higher capacity and smaller size, making them suitable for the needs of various electronic devices.
The working principle of aluminum electrolytic capacitors is based on the ionic conductivity of the electrolyte. Their capacitance values are usually high and they can provide large-capacity energy storage, making them ideal for smoothing power output and stabilizing voltage. At the same time, the polarity characteristics of aluminum electrolytic capacitors require attention to the connection of the positive and negative poles when installing them in a circuit to avoid damage.
Due to its capacity and price advantages, aluminum electrolytic capacitors are widely used in consumer electronics, automotive electronics, industrial equipment and other fields. However, their stability and lifespan in high-temperature environments are relatively short, so appropriate usage conditions and loads need to be considered when designing circuits.
Applications: UPS, energy storage BMS, industrial power supply, PC/PD power supply, etc.
