The method includes dividing the plurality of TMR sensors into test groups. For each test group, the method includes setting the ambient air temperature Tair, applying a voltage pulse at Vdeg and time τp Npulse times until dielectric breakdown, and appending Npulse and τp to a dataset. The method includes fitting a survival fraction of form:versus Npulse, wherein tdeg=Npulse·τp, to determine β and τdb. The method includes determining a temperature rise based on τp, determining, based on the temperature rise, κmr(τdb,Amr), and determiningbased on κmr(τdb,Amr).
