Epoxy Coated Standard Chip Thermistors

NTC Interchangeable Chip Thermistor diagram
Sensor Scientific Epoxy-Coated Standard Chip Thermistors are ideally suited for applications where low cost is a primary consideration. Units are available in resistance values from 100 to 100k ohms @ 25°C. The available resistance vs. temperature curves are industry-standard. The resistance tolerance is usually specified at 25°C. Other calibration temperatures are available on a special order basis. Typical tolerances are ±1, 2, 5, & 10%. Epoxy-Coated Chip Thermistors are widely used in a variety of temperature measurement and compensation applications
