The same type of stability is also observed in thermal shocks between the two extreme values of the temperature range. The tests are performed according to IEC 60068-2-2 and 2-14. 0.6 0.6 Positive threshold Positive threshold 0.5 0.5 0.4 0.4 0.3 0.3 0.2 0.2 Averagedrift R 25 0.1 0.1 Max. drift R Average measureddrift 25 0.0 0.0 Max. measured drift Min. drift R 25 -0.1 -0.1 -0.2 Min. measureddrift -0.2 -0.3 -0.3 -0.4 -0.4 -0.5 -0.5 Negative threshold Negative threshold -0.6 -0.6 0 2000 4000 6000 8000 10 000 0 250 500 750 1000 1250 1500 1750 2000 Time (h) Nr Cycles Fig. 1 - R Drift after Storage at 125 C for 0603 Case Fig. 3 - R Drift in Thermal Shocks -40 C, 15 min/125 C, 15 min 25 C 25 C 0.6 Positive threshold 0.5 0.4 0.3 Average measureddrift 0.2 0.1 Max. measured drift 0.0 -0.1 Min. measureddrift -0.2 -0.3 -0.4 -0.5 Negative threshold -0.6 0 2000 4000 6000 8000 10 000 Time (h) Fig. 2 - Drift in Storage at 125 C for 0402 Case Revision: 05-Jun-2018 Document Number: 29151 2 For technical questions, contact: nlr vishay.com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
