RH1020 Total Dose Test RH1020-CQ84V

D/C 9839- L/C 5962F9096505QTCOJ4Z0

This lot of parts was fabricated at Lockheed-Martin Federal Systems.

TID: There was no change in I_CC during the irradiation a level of 125 krad (Si). The dose rate was 12.95 rad (min) in a Cobalt-60 facility. The parts were monitored (I_CC) in situ and were in a Pb/Al box per Method 1019.5.

Note:

For most tests, the parts were irradiated and tested in two batches with the control sample also tested with each batch. This was done as a result of the limited capacity of the radiation chamber; only two samples could be irradiated at a time.
