DESIGN-IN SUPPORT RELIABILITY INFORMATION For range, complete Computation, 1 to 7at any temperaturemg After a test of storage within the temperature the drift Curve of electrical resistance at 25 °Cvisit: is always lower than ± 0.5 % (see typical figures below for drift after storage during 10 000 h at maximal temperature 125 °C). 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.
