Aluminum-polymer capacitors, specifically the CAP ALUM POLY 33UF 20 20V SMD type, offer a capacity of 33 microfarads at 20 volts. These components are constructed with aluminum and polymer materials for high efficiency. They adhere to metric dimensions (2917 or 7343) and exhibit low resistance of 40 milliohms. The capacitors also meet stringent standards of 1000 hours at a temperature of 125 degrees Celsius.
