Recommended solder pad layout
A = 5,5 mm
B = 1,5 mm
C = 4,2 mm
D = 7,2 mm
Recommended soldering temperature profiles
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 45C
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.
