Semitec’s AT-2 series thermistors are a very popular and widely used range of NTC thermistors. They were the first to use lead-frame technology in production to create consistently accurate ±1% tolerances for both the resistance and B-values.
This production innovation meant they could be supplied at significantly lower-cost than other high-accuracy NTCs. 103AT-2s are especially still at the forefront of many circuit designs including gas-gauge sensing in medical battery applications.
The rigid lead AT-2 format benefits both sensor assembly and p.c.b. mounting. Flexible lead versions (AT-4) and tape/reel types (AT-5) are also possible using the same range of NTC elements.
