Honeywell 135-204QAG-J01 Temperature Sensor: A Clear Look at This 200 kOhm NTC Thermistor
The Honeywell 135-204QAG-J01 temperature sensor is a high-resistance NTC thermistor developed for reliable temperature sensing in electronic and industrial environments. As a Honeywell 135-204QAG-J01 thermistor, it is part of a product family known for rugged construction, broad temperature capability, and straightforward integration into traditional circuit designs.
What Is the Honeywell 135-204QAG-J01?
The Honeywell 135-204QAG-J01 product type is a glass-encapsulated axial lead NTC thermistor from the Honeywell 135 Series. The series is built for applications that need a durable and consistent temperature-sensitive resistor. The sealed glass body improves environmental resistance, while the axial package supports through-hole mounting and compatibility with many established PCB layouts.
Technical Characteristics
The 135-204QAG-J01 NTC thermistor has a nominal resistance of 200 kOhm at 25°C and a B25/85 value of 4261 K. It is supplied in a DO-35 / DO-204AH axial package and is intended for through-hole installation. Like the rest of the Honeywell 135 Series, it supports a very wide operating temperature range, making it attractive for designs exposed to both low and elevated temperatures.
Because it is an NTC component, the 135-204QAG-J01 temperature sensor becomes less resistive as temperature increases. This behavior allows engineers to build simple, responsive sensing circuits for measurement, compensation, protection, and control functions.
Common Application Scenarios
The 135-204QAG-J01 thermistor sensor can be used in industrial control boards, thermal monitoring systems, process electronics, instrumentation, power modules, and environmental sensing assemblies. A higher nominal resistance value may be preferred in designs that are optimized around specific signal conditioning requirements or low-current measurement strategies.
Designers also value the Honeywell 135-204QAG-J01 temperature sensing thermistor because glass encapsulation can improve resistance to contamination and environmental stress. In real-world use, that helps support long-term performance consistency in equipment where maintenance access may be limited.
