New Ametherm High-Accuracy NTC Disc Thermistors Offer R25 From 4 Ohms to 150 Kilohms, Tol to 1%

Ametherm introduced new NTC disc thermistors — recently acquired from Measurement Specialties (formerly RTI Electronics) — featuring a wide range of resistance values and precision tolerances to 1 % for high-accuracy temperature measurement.

Providing designers with a cost-effective alternative to thermocouples in precision circuits, the NTC disc thermistors deliver high stability and maximum sensitivity for temperature measurement, compensation, and control in applications such as fan motor controls, fluid levels, and temperature sensors in a wide range of end products.

With diameters from 2.54 mm to 12.7 mm and profiles from 0.64 mm to 5.33 mm, the devices released feature resistance at 25 °C from 4 Ω to 150 kΩ, Beta from 3000 °K to 5000 °K, and high-temperature operation to + 150 °C. The NTC disc thermistors offer dissipation constants from 3 mw/°C to 17 mw/°C and thermal time constants down to 5 s. RoHS-compliant, the leaded components are available in insulated and non-insulated configurations.
