NTC SMD Thermistors With Nickel Barrier Termination NB 12 - NB 20

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 ofsolderability and enables this chip to meet the requirements of the most severe soldering processes.
