Standard Epoxy NTC Thermistors

TE Connectivity offers a comprehensive range of epoxy coated NTC thermistors with tin plated or PTFE insulated leads. The sensors are available in different sizes from 2.4 to 2.8 mm bead diameters and 32 AWG to 28 AWG wire sizes. They offer a choice of precision temperature tolerance classifications for a wide variety of customer applications, such as temperature measurements, temperature indication, temperature control, and thermal compensation. Thermistor interchangeability is an important factor for cost efficiency as the need for expensive individual calibrations are not necessary as each device will match the published Resistance -Thermistor characteristics for a given thermistor and will be within the specified deviation limits at a single point or over a specific temperature range.
