Honeywell 135-503LAF-J01 Temperature Sensor Explained
The Honeywell 135-503LAF-J01 temperature sensor is an NTC thermistor built for consistent thermal sensing in compact electronic assemblies. As a Honeywell 135-503LAF-J01 thermistor temperature sensor, it is part of Honeywell’s 135 Series and is designed for applications where dependable temperature feedback, small package size, and robust construction all matter.
Key Specifications of Honeywell 135-503LAF-J01
The Honeywell 135-503LAF-J01 NTC thermistor is specified with 50 kOhm resistance at 25°C, ±5% resistance tolerance, and a B25/85 value of 3974K. It uses a DO-35 glass-encapsulated axial package and supports an operating temperature range of -60°C to 300°C. These values make it a practical option for designers who need a rugged board-level thermistor with stable characteristics.
The glass-encapsulated construction is important because it supports reliability in environments where repeated thermal cycling can challenge less robust sensing parts. The axial body style also remains convenient for through-hole assembly, repairs, and legacy-compatible circuit layouts.
Applications for Honeywell 135-503LAF-J01 Thermistor Temperature Sensor
The Honeywell 135-503LAF-J01 temperature sensor can be used in industrial controls, instrumentation, medical electronics, thermal management circuits, and HVAC-related electronic systems. Engineers often choose a 50 kOhm thermistor when they want a particular resistance profile at room temperature along with predictable NTC behavior as heat rises.
Because the Honeywell 135-503LAF-J01 thermistor is part of a recognized Honeywell family, it is also relevant in equipment maintenance and design refresh projects where consistent component behavior matters. In those situations, using a known thermistor family can simplify validation and support continuity in field performance.
