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.

FEATURES

• Fast thermal response

• Commercial, Industrial and Automotive Applications

• PdPtAg Termination
