NTC SMD Thermistors
With Nickel Barrier Termination NB 21 - NB 23
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.
