Fast-Response Thermistors with Tolerances of ±0.2 C
Ametherm today introduced a new series of interchangeable thermistors that provide long-term stability and reliability for high-accuracy temperature sensing, control, and compensation. ACCU-Curve series thermistors are available in a wide range of resistance values, with tight tolerances of ± 0.2 degrees C between 0 and 70 degrees C and fast thermal response times.
Providing designers with faster, less-expensive alternatives to RTD probes and thermocouples — without compromising on accuracy — ACCU-Curve series devices deliver the tight tolerances required for temperature measurement in critical medical instrumentation, and they can be potted in a variety of housings for temperature compensation circuits in industrial and automotive applications.
Offering diameters of 2.4 mm and 32 AWG tinned-copper leads, the epoxy-coated thermistors are available in four resistance values at 25 degrees C — 2.252 kΩ, 3.0 kΩ, 5.0 kΩ, and 10 kΩ — with a dissipation constant of 1 mW/degree C and thermal time constant of 10 sec.
The devices are available direct or through distributors such as Digi-Key and Mouser. Samples and production quantities of the thermistors are available now, with factory lead times of 12 weeks.
