EPCOS multilayer CTVS with AgNiSn termination are designed for the requirements of lead-free
soldering processes only.
Soldering temperature profiles to JEDEC J-STD-020D, IEC 60068-2-58 and ZVEI recommenda-
tions.

3.2
All EPCOS MLVs with nickel barrier and AgPt termination are suitable and fully qualiyfied for lead-
free soldering. The nickel barrier layer is 100% matte tin-plated.
3.3
AgPd-terminated MLVs are mainly designed for conductive adhesion technology on hybrid materi-
al. Additionally MLVs with AgPd termination are suitable for reflow and wave soldering with SnPb
solder.
Note:
Lead-free soldering is not approved for MLVs with AgPd termination.
3.4
The silver-platinum termination is approved for reflow soldering, SnPb soldering and lead-free
with a silver containing solder paste. In case of SnPb soldering, a solder paste Sn62Pb36Ag2 is
recommended. For lead-free reflow soldering, a solder paste SAC, e.g. Sn95.5Ag3.8Cu0.7, is
recommended.
