Recommended Application Voltage
KOCAP’s are solid state capacitors that demonstrate no wearout mechanism when operated within their recommended
guidelines. While the KOCAP can be operated at full rated voltage, most circuit designers seek a minimum level of
assurance in long term reliability which should be demonstrated with data.
A voltage derating can provide the desired level of demonstrated reliability based on industry accepted acceleration
models. Since most applications do require long term reliability, KEMET recommends that designers consider a 10% voltage
derating, according the graphic above, for the maximum steady state voltage.
