Working Principle

Aluminum electrolytic capacitors are made from two aluminum foils with an electrolyte between. The foils act as the electrodes, and the electrolyte is a conductive jelly that acts as the dielectric. One foil is treated with a thin, conducting oxide layer, which is the anode. The anode is connected to the positive terminal of the capacitor. The other foil, which is the cathode, is connected to the negative terminal.

Electric current passes through the electrolyte, which generates ions within the electrolyte. This in turn causes an electrolytic reaction, which makes the electrolyte molecules form a bond with the two electrodes. The molecules are negative and attract the positive ions, and the negative ions attract the positive ions. This creates the capacitance.

The UPM1V121MPD1TA capacitors are specialized electronic components that are designed for reliability and long service life. The capacitors are engineered for high-temperature and vibration resistance, as well as high voltage and surge current capability. Panasonic\'s UPM1V121MPD1TA capacitors are ideal for applications that require pulse response, high ripple current, and long-term reliability.
