NTC thermistors offer thermal time constant of 10s
ACCU-Curve interchangeable NTC thermistors from Ametherm are now being stocked by distributor Digi-Key Electronics. The 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 2.4mm and 32 AWG tinned-copper leads, the epoxy-coated devices are available in four resistance values at 25 °C — 2.252kΩ, 10kΩ, 30kΩ, 100kΩ — with tight tolerances of ± 0.2°C between 0°C and 70°C.
The thermistors feature a dissipation constant of 1mW/°C and thermal time constant of 10s.
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.
