NTC disc thermistors from Ametherm that were acquired from Measurement Specialties (formerly RTI Electronics) are now being stocked by UK-based Rhopoint Components. Ametherm's 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 2.54mm to 12.7mm and profiles from 0.64mm to 5.33mm, the NTC disc thermistors feature resistance at 25°C from 4Ω to 150kΩ, precision tolerances to 1 %, Beta from 3000°K to 5000°K, and high-temperature operation to +150°C. The devices offer dissipation constants from 3mw/°C to 17mw/°C and thermal time constants down to 5s. RoHS-compliant, the leaded components are available in insulated and non-insulated configurations.

"Rhopoint Components has been carrying RTI Electronics and Measurement Specialties products for over 20 years, so we are very pleased to have them round out this offering acquired by Ametherm with our NTC disc thermistors," said Mehdi Samii, vice president of sales and engineering at Ametherm.

"Ametherm's NTC disc thermistors make an exciting addition to our portfolio," said Ian Moore, Sales and Marketing Director at Rhopoint Components. "Ametherm's reputation for high reliability and accuracy is quickly gaining traction in the U.K., and we're pleased to be complementing that with our expert technical support team, which is available in the field and over the phone to help with any customer application."

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