NTC SMD Thermistors
NC 12 – NC 20
Chip thermistors are a high quality and low cost device especially 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 / 30 s).
