Semitec FT/FL Thin Film SMD Thermistors

Semitec thin film FT thermistors can outperform conventional SMD thermistors due to their miniature size, extreme thinness and wide temperature range.  Their small size and thinness allows them to be integrated into products with minimal impact on the available space.

The FT thermistor is available in EIAJ1608, 1005 or 0603 packages (or even smaller) and the axial FL version has silver plated flat ‘lead-wires’ to help simplify the connection process.  A metallised backing is also available to improve thermal response times even further.

Nominal resistance (R25) values of 10k ohms, 50k ohms, 100k ohms and 360k ohms are available as standard.  Other resistance values available in request for volume applications.  Point calibrations also possible to enhance spot temperature accuracy.
