Aluminum electrolytic capacitors: ALS71G153NT400 application field and working principle

Aluminum electrolytic capacitors, also known as aluminum electrolytic capacitors, are mainly composed of a metal oxide film as the dielectric and a positive electrolyte contact as the anode. Its capacitance value and size are determined by the thickness of the oxide film, which is generally expressed by the value of the capacitance. Aluminum electrolytic capacitors are widely used in various types of electronic devices for acoustics, high-frequency signaling, and insulation.

The ALS71G153NT400 aluminum electrolytic capacitor is an ultra-small volume resistor product, which can be used in the output stage of car navigation and GPS, car power amplifier, telephone set circuit, computer adapter, etc. Its size is only 3.2 × 1.6 × 1.25mm, and its weight is only 0.3g. It has the characteristics of high stability, low equivalent series resistance (ESR) and high reliability. In addition, the ALS71G153NT400 aluminum electrolytic capacitor also has a long life, and it is especially suitable for high current load saving.

The working principle of the ALS71G153NT400 aluminum electrolytic capacitor is based on its unique metal oxide film, and its capacitance is very large. The positive electrode is made of pure aluminum foil and is coated with a layer of metal oxide film. When the capacitor is connected to the power supply, the oxide film layer is charged. The charge on the positive electrode is attracted to the negative electrode, and the positive electrode charge is stored in the capacitor. When the capacitor is charged, electrons flow from the negative electrode to the positive electrode, forming a current, and at the same time a certain voltage is generated on the capacitor. When the current is stopped, the voltage in the capacitor is maintained, and the capacitor is charged. This is the working principle of the ALS71G153NT400 aluminum electrolytic capacitor.

In summary, the ALS71G153NT400 aluminum electrolytic capacitor is a product with superior performance and unique structure. It is widely used in various electronic devices, and its use range is very wide. Its working principle is the accumulation of charge on the positive electrode of the capacitor, which is attracted to the negative electrode, and the stored charge remains in the capacitor, providing the required energy to various electronic devices.
