TNR™ Ceramic Varistor Use-by Date

The use-by date for TNR™ Ceramic Varistors is within one year of the date of purchase.
Since varistors are solid state products, depending on storage conditions, they experience almost no degradation over time. As a rule of thumb, the use-by date is within one year of purchase for an unopened package. If more than a year has passed, check the solderability of the leads before using.
