1.3
Silver-platinum terminations are mainly used for the large case sizes 1812 and 2220. The silver-
platinum termination is approved for reflow soldering, SnPb soldering and lead-free soldering with
a silver containing solder paste. In case of SnPb soldering, a solder paste Sn62Pb36Ag2 is rec-
ommended. For lead-free reflow soldering, a solder paste SAC, e.g. Sn95.5Ag3.8Cu0.7, is rec-
ommended.
