Interchangeable Chip Thermistors

Sensor Scientific interchangeable chip thermistors are ideally suited for applications requiring a high-precision temperature sensor, without a high cost. Interchangeability eliminates the burden of individual calibration. Units are available in resistance values from 2k ohms to 100k ohms @ 25°C. The available resistance vs. temperature curves (SSi curves C, D, E & Y) are industry-standard. Interchangeable wafer thermistors are widely used in the medical, automotive, aerospace, HVAC, marine electronic, and instrumentation industries in a variety of temperature measurement, control, and compensation applications. If a standard unit does not meet your needs, customized tolerances, resistance values, temperature ranges, and termination options are available. Design assistance is also available.

Features:

  • High Accuracy
  • High Stability
  • Interchangeable From 0°C to 70°C
  • Operating Temperature Range: -40°C to 150°C
  • Dissipation Constant: 1.5 mW/°C Typ. in still air
