Honeywell 135-234QBF-J01 Temperature Sensor: A Useful Guide to This 230 kOhm NTC Thermistor
The Honeywell 135-234QBF-J01 temperature sensor is a discrete NTC thermistor designed for engineers who need dependable thermal response in a compact, durable package. As a Honeywell 135-234QBF-J01 thermistor, it belongs to the well-known Honeywell 135 Series, a family of glass-encapsulated axial thermistors used in industrial, electronic, and control-oriented applications.
What Type of Sensor Is the Honeywell 135-234QBF-J01?
The Honeywell 135-234QBF-J01 product type is an NTC thermistor with an axial lead configuration and hermetically sealed glass body. This design supports resistance to environmental stress while maintaining a compact footprint suitable for through-hole mounting. For many designers, that combination offers a strong balance between reliability, serviceability, and straightforward integration.
Main Technical Features
The Honeywell 135-234QBF-J01 NTC thermistor has a nominal resistance of 230 kOhm at 25°C and a listed tolerance of 5%. It is provided in a DO-35 axial package and is intended for through-hole installation. Like other Honeywell 135 Series thermistors, it is associated with a broad operating temperature range extending from very low temperatures to elevated thermal conditions often found in demanding equipment.
The sensing principle is simple but highly effective: as temperature rises, the resistance of the Honeywell 135-234QBF-J01 temperature sensor falls. This predictable analog response makes it useful for thermal feedback, over-temperature detection, circuit compensation, and control logic built around resistance change.
Where the Honeywell 135-234QBF-J01 Fits Best
The Honeywell 135-234QBF-J01 thermistor sensor may be considered for industrial controls, precision electronics, laboratory equipment, environmental monitoring circuits, and thermal regulation assemblies. Because the part combines a relatively high nominal resistance with a 5% tolerance figure, it can be relevant in applications where tighter resistance matching is desirable.
Another practical advantage of the Honeywell 135-234QBF-J01 temperature sensing thermistor is construction quality. The glass-encapsulated format helps protect the sensing element, and the axial leads simplify integration into circuits that still rely on dependable through-hole components.

FAQ
What does the 135-234QBF-J01 do?
The Honeywell 135-234QBF-J01 measures temperature indirectly by changing resistance in response to heat. It is an NTC thermistor, so the resistance decreases as temperature increases. This behavior makes it useful for sensing, protection, and compensation circuits.
Why is a 5% tolerance important for the Honeywell 135-234QBF-J01?
A 5% tolerance can be useful in applications where designers want closer alignment to the nominal resistance value at 25°C. That may improve consistency across assemblies, especially in circuits that depend on predictable sensor behavior.
Is the 135-234QBF-J01 a good option for industrial electronics?
Yes. Its glass-encapsulated construction, axial package, and wide operating temperature capability make it relevant for industrial and control-oriented systems where durable analog temperature sensing is required.
How is the 135-234QBF-J01 installed?
This part is intended for through-hole mounting in a DO-35 style axial format. That makes it suitable for many conventional PCB designs and equipment platforms that continue to use mechanically secure through-hole components.
Why would a designer choose the Honeywell 135-234QBF-J01 instead of another temperature sensor?
A designer may prefer it for its combination of rugged glass-sealed construction, analog simplicity, relatively tight tolerance, and compatibility with proven circuit architectures. In many real applications, those qualities are more valuable than unnecessary complexity.
