This capacitor is a high-reliability, surface-mount-capable device designed specifically for demanding applications that require high levels of accuracy and reliability. The ALS81A122DF400 is an aluminum electrolytic capacitor with a rated voltage of 16 volts and a capacitance of 100μF. It is also designed with a temperature range of -40°C to +105°C.

Application Field

This capacitor can be used for a range of applications. Examples of these include: power supplies, power amplifiers, current limiters, audio equipment, motor control systems, digital circuits, voltage regulators, and LED driver circuits. Due to its low impedance, its construction is ideal for extremely high ripple current rating. This makes it perfect for high-current applications such as power applications and where high voltage spikes are expected.

Working Principle

The ALS81A122DF400 is an aluminum electrolytic capacitor, meaning it consists of an electrolyte, organic solvent, and aluminum- or tantalum-oxide anode. The aluminum or tantalum anode is processed into a porous form and is soaked with organic electrolyte, while the electrolyte is soaked with aqueous electrolyte. As the current passes through the anode, the electrolyte is heated. This causes the electrolyte to break down into its elemental components and form a thin barrier of aluminum oxide. This oxide layer acts as an insulating medium that imparts stability to the applied voltage. This feature, along with the corrosion-resistant properties of the aluminum and tantalum, makes the ALS81A122DF400 capacitor resistant to environmental factors, including temperature, vibration, shock, and humidity.

This aluminum electrolytic capacitor also has a wide operating temperature range of -40°C to +105°C, making it suitable for a wide variety of environmental conditions. Additionally, the high-temperature solderability makes the ALS81A122DF400 an ideal choice for difficult soldering processes such as surface-mount applications. This is because its organic electrolyte will not leak out of the capacitor when exposed to higher temperatures.
