Aluminum electrolytic capacitors are widely used in almost all electrical and electronic devices and circuits, especially on the output side of the power supply, and find many application fields. The ALS70H473QT200 is one of a wide range of aluminum electrolytic capacitors from Vishay Sprague. In this article, the application field and working principle of the ALS70H473QT200 will be discussed.

The ALS70H473QT200 is a type of low-ESR (Equivalent Series Resistance) aluminum electrolytic capacitor from Vishay Sprague. It is designed to improve the stability and reliability of electronic devices and circuits, especially on the output side of a power supply. The ALS70H473QT200 is an ideal component for applications that require higher levels of power dissipation, such as automotive, audio, industrial, and avionics. It is also ideal for high-frequency applications, such as ultrasonic transducers, RFID, telecom, video, and medical imaging.

The ALS70H473QT200 is a ceramic-based aluminum electrolytic capacitor and is ideal for applications with higher ripple currents. The capacitor has a capacitance range of 4.7uF-100uF, a voltage rating of 70V DC, and an endurance rating of 8000 to 10000 hours at a rated temperature of 85˚C. The ALS70H473QT200 is available with either leaded or surface mount termination.

The working principle of the ALS70H473QT200 is based on the principle of electrostatic capacitance. This capacitor consists of an electrolytic aluminum foil that is rolled with a dielectric material. The two ends of the electrolytic aluminum foil are attached to the positive and negative terminals of a DC power source. As a result, electric charges of opposite polarities build up on the two ends of the electrolytic aluminum foil and create a capacitance between them. The capacitance of the ALS70H473QT200 is affected by various factors such as its dielectric material, the area of the aluminum foil and the thickness of the dielectric.

In conclusion, the ALS70H473QT200 is a type of low-ESR aluminum electrolytic capacitor from Vishay Sprague. It is an ideal component for applications that require higher levels of power dissipation, such as automotive, audio, industrial, and avionics. The working principle of this capacitor is based on the principle of electrostatic capacitance. The capacitor has a capacitance range of 4.7uF-100uF, a voltage rating of 70V DC, and an endurance rating of 8000 to 10000 hours at a rated temperature of 85˚C. It is also available with either leaded or surface mount termination.
