The components should be soldered within 6 months after delivery from EPCOS. The parts
are to be left in the original packing in order to avoid any soldering problems caused by
oxidized terminals.
Storage temperature: -25 to 45°C
Relative humidity: <75% annual average, <95% on max. 30 days in a year.
The usage of mild, non activated fluxes for soldering is recommended, as well as a proper
cleaning of the PCB.
