The NT73 negative tempco thermistors are mechanically strong and feature a low profile. The thermistors feature anti-leaching nickel barrier terminations (90/10 solder plated, standard) and twelve standard resistance values from 1.0 kΩ through 150 kΩ. Sizes 0603, 0805, and 1206 are available. Dependent upon which size is selected, resistance tolerances of ± 3%, ± 5%, ± 10%, and ± 15% are offered. A power rating of 5 mW is standard with beta constants of 3200K, 3500K, 3700K, 3800K, and 4100K (at 25°C/75°C). Operating temperature range is 55°C to +125°C and the device is suitable for reflow and wave soldering.
