For example, the failure rate of a capacitor is in actuality related strongly to its energy storage, which is proportional to the square of the rated voltage, and yet in the MIL Handbook there is no reliability factor for the rated voltage, only for the capacitance.
Capacitor reliability is vital for all electronic systems, which may help to explain why the NASA Electronic Parts and Pack-aging (NEPP) program has continuously funded studies on the reliability issues of various capacitor technologies.
L = LR x (ER/EO)3 x (8 x TR/TO) In film capacitors, the effect of reducing temperature is like the aluminum electrolytic, but the effect of voltage derating is much greater. Other factors to consider that affect capacitor reliability include humidity, vibration, thermal shock, storage time and the number of large-swing charge-discharge cycles.
Chip capacitors destined for high reliability testing are often designed with an added margin of safety, namely maximization of the dielectric thickness, and tested extensively for electrical properties prior to burn-in (e.g., capacitance, dissipation factor, and insulation resistance).
It is the case, therefore, that the failure rate of the bank is approximately equal to the number of capaci-tors in the bank multiplied by the failure rate of each capacitor. It is generally true that smaller capacitors (CV rating) are more reliable than larger capacitors.
This basically means that for a given capacitor family (type, such as CDE 550C), temperature, and voltage derating, the failure rate is proportional to the product of the rated voltage and the square root of the capacitance.
