A capacitor is made up of a housing; a first plurality of capacitors within the housing; a second plurality of capacitors within the housing; a first electrode coupled to a first terminal, with the first terminal being electrically contactable outside the housing; a second electrode coupled to a second terminal, with the second terminal being contactable outside the housing; a threshold circuit that compares performance of the first plurality of capacitors with performance of the second plurality of capacitors, detects an unbalance, and generates an output signal; and a signal output coupled to the threshold circuit, the signal output being accessible outside the housing. In another embodiment the capacitor has a housing; a first electrode contactable from outside the housing, a second electrode contactable from outside the housing, and an unbalance detection output contactable from outside the housing, wherein an unbalance detection signal indicative of a degree of unbalance.
