In collaboration with Nasa Glenn Research Center, CISSOID components have shown an operational temperature range from -195°C to +300°C.

The voltage regulator (CHT-LDO-033-TO3) and the Voltage reference (CHT-BG3M-025-TO39) have been tested by GRS from -195°C to 100°C and by CISSOID from 25°C to 300°C ambiant temperature. Both circuits are operational in this very large temperature range. The voltage reference shows a global precision of 5% on the complete temperature range. The voltage regulator present a global precision of 6%.

Both circuit can stop and start at extreme low and high temperature.

The 555 Time (CHT-555-TO8) has also been tested at low temperature by GRS and is under test at high temperature by CISSOID.

Some temperature cycling have been made but are not significant.


CISSOID thanks Glenn Research Center for Exreme low temperature tests.
