The NTC disc thermistors recently acquired by Ametherm from Measurement Specialties (formerly RTI Electronics) are now being stocked by Mouser Electronics. The 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 thermistors feature resistance at 25 °C from 4 Ω to 150 kΩ, precision tolerances to 1 %, Beta from 3000 °K to 5000 °K, and high-temperature operation to + 150 °C. The devices 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.

"NTC disc thermistors make a great addition to our growing offering of Ametherm products," said Andy Kerr, Mouser Electronics vice president of passives. "For our customers, the devices' wide range of resistance values and precision tolerances provide the ideal solution for high-accuracy temperature measurement. We couldn't be more excited to have them in stock and readily available."

"Our NTC disc thermistors provide designers with a cost-effective alternative to thermocouples, helping them lower overall solution costs while delivering the precision they require," said Mehdi Samii, vice president of engineering at Ametherm.
