Selected Category：Metal Oxide Varistors > Reliability
TNR™ ceramic varistors have a semi-permanent lifespan, when used within their rated usage temperature and circuit voltage and not subject to external stresses.
As ceramic varistors deteriorate, their leakage current increases. The degree of deterioration can be determined by measuring current leakage.
We can provide the Failures in Time (FIT value) and Mean Time To Failure (MTTF) for TNR™ Ceramic Varistors.
