Tantalum Capacitor » Electronics Notes

Tantalum capacitors are a specific form of electrolytic capacitor. Unlike the more familiar aluminium electrolytic capacitor, tantalum ones are much smaller and offer a very high level of capacitance for a given volume and weight. They also posses a low ESR (equivalent series resistance) than aluminium electrolytics along with a higher ...
