Mouser Electronics now Stocks Ametherm's NTC Disc Thermistors

Ametherm today announced that its NTC disc thermistors recently acquired from Measurement Specialties (formerly RTI Electronics) are now being stocked by Mouser Electronics. The components are available worldwide via Mouser's award-winning website,, and its comprehensive resource catalogs.

Manufactured in the company's Carson City, Nevada, facility, Ametherm's NTC disc thermistors, available from Mouser Electronics, 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 NTC disc thermistors feature resistance at 25 °C from 4 ohms to 150 kilohms, 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. "We are proud to make these components available to meet the needs of Mouser's customers."

Samples and production quantities of the NTC disc thermistors are available now, with lead times of five to six weeks for large orders.
