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.

A safe capacitor comprising:
- a first external termination and a second external termination;
- at least one capacitive unit comprising a first conductor and a second conductor wherein said first conductor is electrically connected to said first external termination and said second conductor is electrically connected to said second external termination;
- and
- at least one safe circuit comprising a first contact pad and a second contact pad with a resistive electronic component electrically connected between said first contact pad and said second contact pad wherein said first contact pad is in electrical contact with said first external termination and said second contact pad is in electrical contact with said second external termination further comprising an internal termination with the capacitive unit connected between said first external termination and said internal termination and electrically connected between said second external termination and said internal termination.
