NTC Accurate Thermistors
NP30 - NJ 28 – NI 24 – NK 20
High precision resistance and an outstanding ability to
reproduce the sensibility index B, make these ranges of
products the types of thermistors ideal for temperature
measurement applications.
Leaded or unleaded, these small size and rapid response
time thermistors are able to meet the most accurate
requirements.
