1557: C/C/C (-20/-20/+10). Mean noise >200e for some ROCs, dead trimbits, failed trimming and mean noise >300e in ROC 4. IV: 0.20 uA at +10 C, slope 1.08
1558: C/C/C (-20/-20/+10). Mean noise >200e for some ROCs, dead trimbits in ROCs 2 and 12, mean noise just above 300e for ROC 2, possibly C* module. IV: 0.27 uA at +10 C, slope 1.07
1559: B/B/B (-20/-20/+10). Electrical grade is B due to mean noise >200e for some ROCs. IV: 0.23 uA at +10 C, slope 1.09
1560: B/B/B (-20/-20/+10). Electrical grade is B due to mean noise >200e for some ROCs. IV: 0.24 uA at +10 C, slope 1.09 |
