Honeywell 111-802EAJ-901 Temp Sensing Thermistor Overview
What Is the Honeywell 111-802EAJ-901 Temperature Sensing Thermistor?
The Honeywell 111-802EAJ-901 temp sensing thermistor is an NTC thermistor from Honeywell’s 111 Series, a line known for miniature glass bead construction and broad thermal capability. This Honeywell 111-802EAJ-901 temperature sensing thermistor is described by distributors as an 8,000 Ohm bead-style thermistor with through-hole mounting. For technical teams evaluating compact thermal components, the part stands out as a small-form sensing element intended for precise resistance-based temperature behavior.
Available references list the Honeywell 111-802EAJ-901 temp sensing thermistor with a nominal resistance of 8 kOhm at 25°C and a resistance tolerance of ±20%. It is also associated with an operating temperature range of -60°C to 300°C, which is one of the defining strengths of the broader 111 Series family. The through-hole bead-glass format supports direct integration into compact assemblies and specialized sensing layouts where larger packaged probes would not be ideal.
Technical Significance of the Honeywell 111-802EAJ-901
In practice, the Honeywell 111-802EAJ-901 thermistor is most relevant where miniature size and responsive thermal behavior are priorities. A glass bead NTC element can react quickly because it has relatively low thermal mass. That is useful in systems that monitor rapidly changing temperatures or where the sensing point is physically restricted.
The 111 Series is also known for hermetically sealed glass construction and application flexibility in low heat capacity environments. For designers comparing Honeywell 111-802EAJ-901 temperature sensor options, this means the part can be considered for instrumentation, compensation networks, embedded monitoring systems, and tightly packaged thermal assemblies where small dimensions matter.
Why the Honeywell 111-802EAJ-901 Is Often Researched
People searching for a Honeywell 111-802EAJ-901 temp sensing thermistor are usually trying to verify resistance, tolerance, package style, and family characteristics before integrating the part into a design or parts list. Those are the specifications that shape actual system performance. An 8 kOhm NTC thermistor can behave very differently from a 2 kOhm or 100 kOhm alternative in the same environment, so precise part selection matters.
That is why the Honeywell 111-802EAJ-901 temperature sensing thermistor remains a technical reference point rather than just a catalog entry. For more information about Honeywell, this link may help.
FAQ
What is the nominal resistance of the Honeywell 111-802EAJ-901?
The nominal resistance is 8,000 Ohm at 25°C, according to current distributor listings.
What type of sensor is the Honeywell 111-802EAJ-901?
It is an NTC thermistor. Its resistance decreases as temperature rises, making it useful in sensing and compensation circuits.
What package style does this part use?
The part is described as a bead-glass thermistor with through-hole mounting, suitable for compact circuit and assembly integration.
What temperature range is supported?
Available product references list an operating range from -60°C to 300°C.
Why might engineers choose an 8 kOhm thermistor?
The resistance value affects how the component interacts with measurement and control circuits. An 8 kOhm thermistor may better match certain circuit designs than lower or higher resistance options.
Is the 111-802EAJ-901 meant for large external probe applications?
Not typically. Its strength lies in compact thermal sensing, embedded designs, and systems where a miniature sensing element is more suitable than a large packaged probe.
