Honeywell 142-302LAG-RB2 Thermistor: A Practical Guide to Temperature Sensing
The Honeywell 142-302LAG-RB2 thermistor is a discrete temperature sensing component designed for reliable resistance-based temperature measurement in electronic systems. For engineers and buyers comparing compact sensing parts, this model stands out as a practical option for applications that need stable thermal response, board-mount convenience, and proven NTC thermistor behavior.
What Is the Honeywell 142-302LAG-RB2 Thermistor?
The Honeywell 142-302LAG-RB2 temperature sensor is commonly listed as an NTC thermistor with a nominal resistance of 3 kOhm. It is part of Honeywell’s discrete thermistor offering and is described as a disc thermistor with leads and epoxy construction. That structure supports straightforward integration into assemblies where cost-effective temperature monitoring is needed without moving to a more complex sensing platform.
Main Technical Features
When people search for a Honeywell 142-302LAG-RB2 thermistor, they usually want a component that is simple to use yet dependable over time. This model is associated with a 3 kOhm resistance value and a 10% tolerance, and it is described as a small disc-style part with tinned copper leads. Honeywell literature also highlights traits such as cost effectiveness, PC board mountability, and rugged design.
Those characteristics make a difference in real projects. An NTC device changes resistance as temperature changes, so it can be used in measurement, compensation, control, and thermal protection circuits. In practical terms, the Honeywell 142-302LAG-RB2 thermistor can support systems that need to monitor temperature shifts without requiring a large sensor package or complicated signal conditioning.
Typical Applications for the Honeywell 142-302LAG-RB2 Thermistor
A Honeywell 142-302LAG-RB2 temperature sensor may be considered for HVAC controls, power electronics, battery-related thermal monitoring, environmental sensing assemblies, and general electronic equipment that needs resistance-based temperature feedback. It can also fit designs where PCB mounting and mechanical simplicity are important.
Because the sensing element is based on established NTC thermistor behavior, this component may also be used for temperature compensation in analog circuits, thermal limit functions, and equipment protection strategies. That makes the Honeywell 142-302LAG-RB2 thermistor relevant in both new designs and replacement sourcing scenarios.
