ALS70A393DB025 Working Principle

Aluminum electrolytic capacitors are made of a rolled anode foil which is formed into a cylindrical shape and then placed in a container sealed with an electrolyte. The anode and cathode are connected by an electrolyte made of either a liquid or gel material. When voltage is applied, electrons pass from the anode to the cathode through the electrolyte and create an electric field in the gap between the electrodes. This electric field creates the capacitance.

The ALS70A393DB025 is a long-life type aluminum electrolytic capacitor. Its capacitance is 70μF, rated voltage is 25 V dc, rated temperature is +105°C, and it has a ripple current of 9500 mA at 120 Hz. It has a ±20% tolerance and a lifetime of 2000 to 5000 hours. Additionally, it can withstand leakage current up to 3 mA.
