Abstract
A capacitor with a combined with a resistor and/or fuse is described. This safe capacitor can rapidly discharge through the resistor when shorted. The presence of a fuse in series with the capacitor and results in a resistive failure when this opens during and overcurrent condition. Furthermore, the presence of a resistor in parallel to the capacitor allows the energy to be rapidly dissipated when a failure occurs.
