Semitec HT Series SMD Chip NTC Thermistors

Semitec HT series SMD thermistors are a unique NTC temperature sensor solution.  They utilise a high accuracy NTC thermistor element encapsulated in an SOD-123 plastic package.  This encapsulation gives them superior environmental compared with conventional chip thermistors.

As well as the SOD-123 package, by forming the metal legs into short axial leads, Semitec can also offer the HTF package.  This HTF version is especially useful when monitoring airflow temperatures over a small aperture on a p.c.b. or other electrical circuit.

With R25 values from 3kohms to 100kohms and tolerances as small as +/-1%, the HT and HTF series thermistors can offer a range of SMD temperature sensor solutions for your application.  Custom R25 and B values also  available for very high volume applications.
