This paper presents a prognostics approach which detects the performance degradation of multilayer ceramic capacitors under temperature-humidity-bias conditions, and then predicts remaining useful life. In the tests, three performance parameters (capacitance, dissipation factor and insulation resistance) were monitored in-situ. By comparing the predicted results with the experimental results, the prognostics approach provided advanced warning of failures for capacitors and predicted their remaining useful life.
