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 proper cleaning of the PCB. The components are suited to Pb-free soldering.
