Kevin, Your calculation looks in order. To elaborate on our FIT value: 1. We completed qualification testing on 2112 devices from this technology, through 1000 hrs of a highly accelerated temperature and voltage HTOL (high temp operation life). We found no fails. 2. Even without acceleration, we have 2112 * 1000 hrs = 2,100,000 POH; that is 2M Hours of operation life/testing. 3. We have observed no significant issues with this class of devices. 4. The numbers / methods they show below is consistent with JEDEC methods/procedures for interpreting the impact of 30 yrs life.
