Electronic components which are able to work at cryogenic temperatures are demanded in cryogenic instruments, high sensitivity measurement systems, space missions, medical diagnosis among other applications. Different non-cryogenic commercial electronic components have been characterized between room temperature and −196°C. A simple measurement technique, taking advantage of the temperature gradient inside a partially empty LN 2 Dewar vessel has been used. The results of the electrical characterization show that some of these components can be used at cryogenic temperatures with a reasonable performance even if their specifications datasheets state the contrary.
