Honeywell 111-102CAJ-H01 Thermistor Technical Guide

The Honeywell 111-102CAJ-H01 thermistor is part of the Honeywell 111 Series, a product family widely recognized for compact glass-bead thermistor construction and fast thermal response. Engineers searching for Honeywell 111-102CAJ-H01 thermistor specifications are usually focused on stable temperature sensing in compact assemblies where sensitivity, size, and response time all matter. In such applications, the sensor is not just a passive part; it is a critical input element that influences control precision, thermal monitoring, and protective system behavior.

Honeywell describes the 111 Series as hermetically sealed in glass, with relatively uniform size, fast time response, and high sensitivity to electric power. Exact part-level references for the Honeywell 111-102CAJ-H01 thermistor commonly associate it with 1,000 ohm resistance, ±20% tolerance, a 25/85 Beta value of 3068, and a 9.6 mm lead length. That combination places the Honeywell 111-102CAJ-H01 thermistor in a category well suited to low heat capacity applications and tightly constrained assemblies where a small sensing element is required.

Why the Honeywell 111-102CAJ-H01 Matters

Glass-bead NTC thermistors remain highly relevant because they can deliver fast thermal tracking in spaces where larger probes would be impractical. The Honeywell 111-102CAJ-H01 thermistor is especially interesting for designers who need a compact temperature sensor that reacts quickly to changing thermal conditions. Because the 111 Series is hermetically sealed, the family also offers a level of environmental robustness that supports stable use in sensitive assemblies.

Another reason the Honeywell 111-102CAJ-H01 thermistor remains a common search term is application flexibility. Small-form thermistors like this are often considered for medical devices, instrumentation, compact electronics, and tightly packed control circuits.
