Semitec FT/FL Thin Film SMD Thermistors

Semitec thin film FT thermistors can outperform conventional SMD thermistors due to miniature size, extreme thinness (= very quick response time) and wide temperature range.  Their small size and thinness allows them to be integrated into products with minimal impact on 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 connection.

Nominal resistance (R25) values of 10k, 50k, 100k and 360kohms are available.
