Semitec AP-2 Ultra High Accuracy Thermistors

Semitec AP-2 thermistors offer even higher accuracy than our AT-2 series and benefit from a 150°C Tmax rating – making them suitable for automotive applications.  They are accurate to ±0.5°C over –60℃ to +80℃ and because of their stiff lead-wires, are easier to handle than conventional interchangeable thermistors.

All nine resistance values (from 2kΩ to 200kΩ) are readily available from stock and they are fully compliant with RoHS DIRECTIVE 2011/65/EU.
