SM Series SMD NTC Thermistors

Our SM series of SMD NTC thermistors offers a neat surface-mount solution when board level temperature sensing is required.  The SM thermistor is available in package sizes from 0805 down to 0201 and so they can be incorporated in the smallest of spaces.

With R25 and B value accuracies as small as +/-1%, the SM thermistor can be used for highly accurate temperature control as well as general temperature compensation applications.  A wide range of R25 and B values means we can offer a cost-effective solution to match your existing thermistor requirements.

We can also offer bespoke R25 and B values for high volume applications and also offer automotive-grade versions where required.
