No. Process Condition
10 Capacitance aging The capacitors (Class 2) have aging in the capacitance. They may not be used in
precision time constant circuit. In case of the time constant circuit, the evaluation
should be done well.
11 Estimated life and
estimated failure
rate of capacitors
As per the estimated life and the estimated failure rate depend on the temperature
and the voltage. This can be calculated by the equation described in JEITA
RCR-2335B Annex 6 (Informative) Calculation of the estimated lifetime and the
estimated failure rate ( Voltage acceleration coefficient : 3 multiplication rule,
Temperature acceleration coefficient : 10°C rule)
The failure rate can be decreased by reducing the temperature and the voltage but
they will not be guaranteed.
