Aluminum electrolytic capacitors use aluminum and aluminum oxide as an insulating layer to store electrical energy. The ALS81A471DB450 is an aluminum electrolytic capacitor suitable for applications in the automotive industry, power supplies, motor start circuits, switching power supplies, and high frequency inverters. It has an operating temperature range of -40°C to +105°C and is rated to withstand working voltages of 50 volts.

The ALS81A471DB450 aluminum electrolytic capacitor has a p.e.t. (polyethylene terephthalate) sleeve that serves to protect the terminations of the capacitor. The sleeve also prevents the accumulation of dust and moisture on the capacitor’s contacts. The capacitor also has solid electrodes instead of aluminum foil, enabling it to handle higher stresses than standard aluminum electrolytic capacitors.

In addition, the ALS81A471DB450 is a tantalum capacitor, which is praised for its durability and long life expectancy, making it ideal for applications that demand high reliability. The aluminum electrolytic capacitor also features a long rated life of 2000 hours at 105°C, which further adds to its overall reliability. The capacitor is also RoHS compliant and offers low impedance and high pulse current capabilities.

The working principle of the ALS81A471DB450 aluminum electrolytic capacitor involves the diffusion of electric charge through an oxide layer. An electric field is set up across the oxide layer, and this electric field is responsible for establishing an electrostatic force between the surfaces of the anode and the cathode, which in turn creates the capacitor’s capacitance. The amount of charge that can be stored in the capacitor is determined by the size of the oxide layer, the area of the anode and cathode, as well as the distance between the two surfaces.

The ALS81A471DB450 aluminum electrolytic capacitor is ideal for use in a variety of automotive applications, power supplies, motor start circuits, switching power supplies, and high frequency inverters. It possesses excellent long-term reliability and a long lifetime, making it the perfect choice for those applications requiring maximum reliability. The tantalum construction of the capacitor provides further peace of mind, ensuring that it will perform optimally in a wide range of environmental conditions. Additionally, its long rated life of 2000 hours at 105°C, low impedance and high pulse current rating make it an excellent choice for those looking for a versatile, reliable, and long-lasting aluminum electrolytic capacitor.
