NOTE:
1. ΔR’s are not cumulative. For purposes of determining reliability calculations, consider the characteristics shown as figures of merit
and allow no more than ±0.05% ΔR lifetime. Allow proportionately less if the severity of anticipated environmental stress is small
compared to the tests as defined in MIL-PRF-83401.
