Honeywell 175-103LAE-301 NTC Thermistor Guide
The Honeywell 175-103LAE-301 NTC thermistor is a well-defined temperature sensing component used in applications where compact surface-mount sensing is important. Publicly available product data identifies this part as a 10 kOhm NTC thermistor in a 1206 package with ±3% tolerance, making it a relevant choice for engineers who need stable, board-level temperature sensing in compact electronic designs.
What Is the Honeywell 175-103LAE-301 NTC Thermistor?
The Honeywell 175-103LAE-301 is a surface-mount negative temperature coefficient thermistor. In simple terms, its resistance decreases as temperature rises. That behavior makes it useful in sensing, compensation, and thermal monitoring circuits. Because it uses a 1206 package format, it is especially suitable for compact PCB layouts where space efficiency matters.
Honeywell’s 173 and 175 Series thermistors are described as being designed for robotic mounting on rigid or flexible PC boards and for boards with a high density of discrete components. That makes the Honeywell 175-103LAE-301 NTC thermistor particularly relevant in modern electronic assemblies where production efficiency and layout density go hand in hand.
Key Technical Characteristics
The most frequently referenced public characteristics for Honeywell 175-103LAE-301 include a nominal resistance of 10 kOhm at 25°C, ±3% tolerance, and 1206 surface-mount construction. Public distributor documentation also associates this part with the 175 Series end-banded thermistor format, which is widely used where compact sensing and automated assembly are priorities.
Where the Honeywell 175-103LAE-301 Is Commonly Used
NTC thermistors like Honeywell 175-103LAE-301 are commonly used for temperature measurement, circuit compensation, thermal feedback, and device protection. In practice, they can support designs in industrial electronics, control systems, instrumentation, and densely populated electronic boards. Their value comes from fast integration into PCB-based systems without requiring bulky external sensor housings.
Why Engineers Search by Full Code
Users often search phrases such as Honeywell 175-103LAE-301 thermistor, 175-103LAE-301 NTC thermistor, and Honeywell 175-103LAE-301 temperature sensor because exact part-number accuracy matters in electronics. Package size, tolerance, and resistance value all affect design compatibility. A close substitute may look similar on paper while behaving differently in a thermal control circuit.

FAQ
What is 175-103LAE-301?
Honeywell 175-103LAE-301 is an NTC thermistor used for temperature sensing and thermal compensation in electronic circuits. Public listings identify it as a 10 kOhm surface-mount part in a 1206 package.
What does NTC mean in Honeywell 175-103LAE-301 NTC thermistor?
NTC stands for negative temperature coefficient. This means the thermistor’s resistance decreases as the surrounding temperature increases.
Why is the 1206 package important?
The 1206 package helps determine board footprint, assembly compatibility, and layout planning. In PCB design, package size is just as important as the electrical value.
Where can 175-103LAE-301 be used?
It can be used in board-level sensing, thermal monitoring, temperature compensation, and protection circuits across industrial and electronic control applications.
Why do engineers specify the full code instead of just saying 10k thermistor?
Because resistance value alone is not enough. The full manufacturer code reflects package style, tolerance, series design, and sourcing traceability, all of which are important in professional electronics work.
