The Context: Recently acquired from Measurement Specialties, Ametherm's NTC chip
thermistors offer designers a wide range of resistance at 25 °C to choose from, with precision
tolerances to 1 %. The devices feature a dissipation constant of 2 mw/°C and thermal time
constants down to 2 s for fast response times. Providing an alternative to thermocouples in
precision circuits, the NTC chip thermistors deliver high stability and maximum sensitivity for
temperature measurement, compensation, and control in a wide range of end products.
Availability: Offered through Digi-Key, Mouser, Dexter Magnetic Technologies, and PUI,
samples and production quantities of the NTC chip thermistors are available now, with lead
times of six weeks.
