This component should be soldered within 12 months after delivery from EPCOS. They
should be left in their original packings to avoid soldering problems due to oxidized terminals.
Storage temperature:
-25
to 45 °C
Relative humidity: < 75% annual average, < 95% on maximum 30 days in a year.
The usage of mild non-activated fluxes for soldering is recommended, as well as proper
cleaning of the PCB.
The components are suited for Pb-free soldering.
