Storage condition
As far as possible, the components should be employed within 6 months after delivery from
EPCOS.
They should be left in their original packing to avoid soldering problems due to oxidized
contacts.
Storage temperature:
−
25 up to + 45°C.
Relative humidity: < 75 % annual average, < 95 % on max. 30 days in a year.
