NTC SMD Thermistors
NC 12 – NC 20 (PdPtAg Termination)
Chip thermistors are a high quality and low cost device espe-
cially developed for surface mounting applications. They are
widely used for temperature compensation but can also
achieve temperature control of printed circuits. Its silver -
palladium - platinum metallization provides a high degree of
resistance to dewetting of the terminations during soldering
(typically 260°C / 15 s). Parts are suitable for hybrid assem-
bly process, not suitabel for lead free soldering.

a) The visual standards used for evaluation of solder joints
will need to be modified as lead free joints are not as bright
as with tin-lead pastes and the fillet may not be as large.
NB products are compatible with a wide range of soldering
conditions consistent with good manufacturing practice for
surface mount components. This includes Pb free reflow
processes with peak temperatures up to 270ºC.
Recommended profiles for reflow and wave soldering are
shown below for reference.
b) Resin color may darken slightly due to the increase in
temperature required for the new pastes.
c) Lead-free solder pastes do not allow the same self align-
ment as lead containing systems. Standard mounting
pads are acceptable, but machine set up may need to be
modified.
NC products are recommended for lead soldering application
or gluing techniques.
