Description
This NTC Thermistor ensures accurate temperature sensing to within ±0.3⁰C (at 25°C) and are better than ±0.5°C accurate over the range 0°C to 45°C.
Highly versatile, they are widely used by many industries , across diverse applications including battery management within e-vehicles, HVAC, Arduino, and Environment.
During the moulding process, the 103AT-11-11’s sensing tip is sealed to the single-insulated TPE leads to ensure IP67 integrity and therefore can be used where moisture ingress is often a problem to epoxy sealed sensors. .
Easy NTC Thermistor integration is offered to speed up design time
High and low quantities are available
