ALS71A203QH200

Aluminum Electrolytic Capacitors, abbreviated to AEC, are capacitors that have a dry electrolyte as the dielectric instead of a liquid. They are a polarized capacitors with increased power gains over other types of capacitors, and create a higher power to size ratio than other capacitor types. They are most commonly used in audio, switching power supplies, motor and DC/DC converter applications, as well as many other applications.

ALS71A203QH200 is a specific form of aluminum electrolytic capacitor, and it is a capacitor with a low equivalent series resistance (ESR), high ripple current and a high temperature resistance rating (105°C). Its features make it suitable for power conversion and filtering applications that have high temperature and high frequency operating conditions.

The working principle of ALS71A203QH200 is simple to understand. This capacitor is essentially a sealed metal canister with two metal plates inside of it, separated by a thin insulating film of electrolyte. When a voltage is applied to the plates of the capacitor, the electrolyte ionizes and creates a charge balance and form the dielectric layer between the two plates. This creates a capacitance that is a function of the area of the plates and the dielectric constant (K) of the material between them.

Just like all aluminum electrolytic capacitors, ALS71A203QH200 has a wide range of applications. Its high temperature resistance and low ESR makes it a great choice for high power applications. Due to its high ripple current, it is often used in audio circuits for power amplification or signal filtering. It is also commonly used in filter circuits, motor and DC/DC converter applications, and many other power conversion applications.

In conclusion, the ALS71A203QH200 aluminum electrolytic capacitor is a polarized capacitor that offers superior high power and high temperature performance compared to other types of capacitors. It is a great choice for power conversion and filtering applications that require high temperature and high frequency operations. It is also suitable for many high power applications and audio circuits.
