Ametherm’s new NTC chip thermistors are for high-accuracy temperature measurement. Recently acquired from Measurement Specialties, the devices are available in a wide range of resistance values, with precision tolerances to 1 % and fast thermal response times.
Providing designers with an alternative to thermocouples in precision circuits, the NTC chip 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.
Measuring 1.27 mm by 1.27 mm with profiles from 0.5 mm to 3.8 mm, the devices feature resistance at 25 °C from 100 Ω to 500 kΩ, a wide range of TCR values, and high-temperature operation to + 150 °C. The NTC chip thermistors offer a dissipation constant of 2 mw/°C and thermal time constants down to 2 s. RoHS-compliant, the leaded components are available in epoxy-coated and uncoated configurations.
The devices are available direct or through distributors such as Digi-Key, Mouser, Dexter Magnetic Technologies, and PUI.
