... See "Important notes" at the end of this document. Storage Store thermistors only in original packaging. Do not open the package prior to storage. Storage conditions in original packaging: storage temperature humidity 75% annual mean, <95% maximum 30 days per annum, dew precipitation is inadmissible. Do not store thermistors where they are exposed to heat or direct sunlight. Otherwise, the packing material may be deformed or components may stick together, causing problems during mounting ...

... Electrodes/contacts must not be scratched or damaged before/during/after the mounting process. Contacts and housing used for assembly with the thermistor must be clean before mounting. Ensure that adjacent materials are designed for operation at temperatures comparable to the surface temperature of the thermistor. Be sure that surrounding parts and materials can withstand the temperature. ...
