Type GC11 GC14, GC16 Thermometrics Glass Encapsulated NTC Chip Thermistor Description Small glass encapsulated chip thermistors on fine diameter platinum alloy lead wires. Features • Glass encapsulated bead thermistors. • Suitable for temperature measurement, control or compensation applications. • Fast thermal response times. • Suitable for self-heated applications such as liquid level sensing or gas flow measurement. • Operating temperatures range from -40°C to +250°C. • Unaffected by severe environmental exposures, including nuclear radiation. • Intermittent operation up to 450°C is permissible; however, stability will be degraded. • Improved beta tolerance with respect to glass encapsulated beads. • RoHS compliant to 2002/95/CE. Amphenol Advanced Sensors Options • Non-standard resistance tolerances and values • Reference temperature(s) other than 25°C specify. • Custom packaging available. • Welded or soldered extension leads - specify lead material, diameter, length and insulation, if any. • Calibration - specify temperature(s). • Interchangeable pairs or sets, curve matching — specify temperature ranges and tolerance(s). • Special aging and conditioning for high reliability applications. Specifications Thermal and Electrical Properties Note: These thermal and electrical properties are for all small glass encapsulated thermistors. All definitions and test methods are per MIL-PRF-23648.

Consult factory for special resistance tolerances, nonstandard resistances and/or non-standard temperatures. NOTE 2: The zero-power resistance at 25°C, expressed in ohms, is identified by a three-digit code number. The first two digits represent significant figures, and the last digit specifies the number of zeros to follow. Example: 51 kOhms = “513”. The standard resistance values are from the 24-value series decade as specified in Military Standard MS90178. 1.0 / 1.1 / 1.2 / 1.3 / 1.5 / 1.6 / 1.8 / 2.0 / 2.2 / 2.4 / 2.7 / 3.0 3.3 / 3.6 / 3.9 / 4.3 / 4.7 / 5.1 / 5.6 / 6.2 / 6.8 / 7.5 / 8.2 / 9.1 Amphenol Advanced Sensors www.amphenol-sensors.com © 2014 Amphenol Corporation.
