Aluminum electrolytic capacitors are a form of electrolytic capacitor that uses an aluminum foil as the anode and oxide coated on it as the dielectric. The oxide layer is formed as a result of anodic oxidation of the aluminum foil when current is passed through the electrolyte solution and a polarization voltage is applied across terminals of the capacitor. As a result, one of the most important characteristics of these capacitors is that their electrical parameters are highly temperature dependent, making them highly desirable for use in temperature sensitive applications.

The ALS81H682QC250 is a type of aluminum electrolytic capacitor. It is a radial-leaded, non-solid, can-type aluminum electrolytic capacitor, which has a maximum operating temperature of 85°C, capacitance of 68000uF and a rated voltage of 250V. Such capacitors are mainly used in applications such as power supplies, power electronic circuits, electrical equipment and automotive electronics.

The working principle of this type of capacitor is based on the principle of electrolysis. When a power source supplies charge to the electrolytic solution, both anions and cations move toward the electrodes that are adjacent to the anode and cathode, respectively. This movement of charge causes a layer of aluminum oxide to form on the aluminum foil that forms the anode. By providing a current of appropriate magnitude, the oxide layer is held in place, thus allowing the capacitance of the capacitor to increase. The current is then filtered out of the circuit, ensuring that the oxide layer remains intact.

The aluminum electrolytic capacitors, of which the ALS81H682QC250 capacitor is an example, are used in a variety of applications, as their characteristics of low equivalent series resistance (ESR) and low self-heating make them well suited for use in filtering, transmitting and storing electric energy in high-temperature environments, such as high-power motors or power supplies. Moreover, this type of capacitor gives stable performance throughout a wide range of temperature, up to a maximum operating temperature of 85°C, which makes them ideal for use in applications where reliable performance is needed across temperature extremes. Furthermore, due to their low ESR, these capacitors are also used in noise reduction, and in applications where high current is necessary, such as in high-frequency circuits.

Overall, the ALS81H682QC250 capacitor is an aluminum electrolytic capacitor, which is used in a variety of applications due to its low equivalent series resistance, low self-heating, and high current capability. This type of capacitor is highly temperature-dependent, making it well-suited for use in temperature-sensitive applications. Its stable performance throughout a wide range of temperature, up to a maximum operating temperature of 85°C, make it ideal for use in applications where reliable performance is needed across wide temperature ranges.
