The ET-3H thermistor was originally developed for clinical thermometer applications.
With bead sizes of 1.4mm (or less) and flexible wire. Its fast response and high accuracy make it a universal choice for low-cost, clinical thermometers.
R37 tolerances of ±1% or smaller and matched resistance groups help to minimise unit cost whilst maximising sensor accuracy.
