Figure 26.
Failures caused by systematic degradation can be described by the Arrhenius model. The most critical
parameter (IR) is the Insulation Resistance (i.e. leakage current). The drop of IR below a lower limit (e.g. 1 M Ω )
is used as the failure criterion, see Figure 26 . It should be noted that the wear-out mechanisms occurring in the
MLCC capacitors are not reversible but cumulative over time.
