Honeywell 135-103FAD-J01 10K NTC Thermistor Explained

The 135-103FAD-J01 NTC thermistor is a 10K temperature sensing component from the Honeywell 135 Series. This exact part number is associated with a nominal resistance of 10,000 ohms at 25°C and a 2% tolerance at 25°C, making it an attractive option for designs that need tighter resistance accuracy at the reference point. For engineers working with temperature measurement, compensation, and control circuits, that tighter tolerance can help reduce calibration effort and improve consistency from one assembly to the next.

What the Honeywell 135-103FAD-J01 Offers

The Honeywell 135-103FAD-J01 combines part-specific electrical value with the broader benefits of the 135 Series platform. Honeywell describes the 135 Series as a rugged, hermetically sealed, glass encapsulated chip thermistor family in a DO-35 type package. The series is designed for a wide operating temperature range from -60°C to 300°C, which is broader than many standard thermistor options used in routine electronics work.

Technical Features of the Honeywell 135-103FAD-J01

The Honeywell 135-103FAD-J01 has a nominal 10 kOhm resistance at 25°C and 2% tolerance at 25°C. In the 135 Series construction, designers also get a typical dissipation constant of 2.5 mW/°C in still air, a typical time constant of 4 seconds in air, a maximum body diameter of about 2.0 mm, and tinned copper-clad steel leads. These details are important because they affect thermal responsiveness, power handling in measurement circuits, assembly method, and durability over time.

The part is also associated with Curve 10 Type F data for its resistance-temperature relationship. In practical circuit design, that means the Honeywell 135-103FAD-J01 should be selected not only by nominal resistance, but also by the required curve match across the intended operating range.

Typical Use Cases

The Honeywell 135-103FAD-J01 10K NTC thermistor is commonly relevant in industrial controls, HVAC electronics, instrumentation, thermal compensation networks, and embedded systems that rely on known thermistor behavior. A 10K thermistor remains one of the most searched temperature sensing formats because it is widely used in monitoring and control applications across both industrial and commercial electronics.

Search terms such as Honeywell 135-103FAD-J01 thermistor, Honeywell 135-103FAD-J01 10K NTC thermistor, and Honeywell 10K temperature sensor are usually driven by engineers who need direct compatibility with an existing design or maintenance requirement.
