Ametherm announced that its ACCU-Curve interchangeable NTC thermistors are now being stocked by its valued distributor Digi-Key Electronics. The components are available worldwide via Digi-Key’s online catalog.
Ametherm’s ACCU-Curve NTC thermistors deliver long-term stability and reliability for high-accuracy temperature sensing, control, and compensation in medical, industrial, and automotive applications. The devices offer interchangeability over a broad temperature range and eliminate the need to individually calibrate or provide circuit compensation for part variability.
Offering diameters of 2.4 mm and 32 AWG tinned-copper leads, the epoxy-coated devices are available in four resistance values at 25 °C — 2.252 kΩ, 10 kΩ, 30 kΩ, 100 kΩ — with tight tolerances of ± 0.2 °C between 0 °C and 70 °C. The thermistors feature a dissipation constant of 1 mW/°C and thermal time constant of 10 s.
“Our ACCU-Curve series NTC thermistors provide designers with faster, less-expensive alternatives to RTD probes and thermocouples — without compromising on accuracy,” said Mehdi Samii, vice president of engineering at Ametherm. “We are proud to make these benefits available to Digi-Key’s customers.”
ACCU-Curve series thermistors deliver the tight tolerances required for accurate temperature measurement in critical medical instrumentation and can be potted in a variety of housings for temperature compensation circuits in industrial and automotive applications.
Samples and production quantities of the thermistors are available now, with lead times of 12 weeks for large orders.
