Chip thermistors are high quality and low cost devices
especially developed for surface mounting applications. They
are widely used for temperature compensation but can also
achieve temperature control of printed circuits.
A nickel barrier metallization provides outstanding qualities of
solderability and enables this chip to meet the requirements
of the most severe soldering processes including lead free
soldering with peak termperatures up to 270ºC.
Resistance - Temperature characteristics: pages 29 to 33.
