Yes, your heard right. There are 1 farad capacitors. In fact, there are 3.3 farad capacitors. They are only suitable for such things as memory backup and the like because they have a high internal resistance. That is the trade-off that alows such a high capacitance. They are also low voltage (5-6.3V). Also, if you heard a *rummer* it probably wasn't in electrical engineering. They spell it *rumor*. A rummer is " a large drinking cup or glass" which has little to do with capacitors unless it is a glass dielectric capacitor which would not be one farad. By the way, this was not written by the above named person (Wayne). He can't spell rumor either. John Blankenagel tekig!johnbl
