Semitec ET Miniature Epoxy NTC Thermistor
Originally designed for clinical thermometer applications, this small bead NTC thermistor is very versatile and suitable for a wide range of applications. The fast response, high accuracy and precise format make it a universal choice for low-cost applications.
ET series thermistors are mounted on stiff or flexible lead-wires giving users a choice of rigidity in their application. The ET-1 version has a built-in strain-relief point to help minimise the bead size and thus maximise the speed of response. ET-3H versions have lacquered lead-wires which help to insulate the thermistor and provide environmental protection in heat detector applications.
As well as a wide range of nominal R25 resistance values, ET thermistors can be point-calibrated at 37°C with tolerances of ±1% or less. Also highly accurate matched R37 resistance groups (with accuracy +/-0.1°C or smaller) can be produced to help minimise unit cost whilst maximising sensor accuracy in high volume applications.
