Description
Maintain precise thermal control over your 3D printer’s hotend and heated bed with this high-reliability 100k NTC thermistor. A thermistor is a thermally sensitive resistor that exhibits a significant, measurable change in resistance relative to temperature variations. This NTC (Negative Temperature Coefficient) sensor is specifically calibrated to decrease in resistance as temperatures rise, providing your printer’s controller with the granular data needed to manage heating elements effectively.
Because thermistor behavior is non-linear, this sensor is designed to follow a standard, pre-defined resistance curve. This ensures compatibility with most mainstream 3D printer firmware (such as Marlin), allowing for accurate, real-time temperature monitoring and adjustment. With a 1-meter cable, this sensor offers the reach required for a variety of printer frames, from standard compact models to larger builds.
Key Features
- High Sensitivity: 100k Ohm NTC design provides excellent accuracy for critical extrusion and bed-level thermal management.
- Standardized Calibration: Built to industry-standard specs (R25=100k, B25/50=3950k) for broad firmware compatibility.
- Precision Engineering: High-quality construction with ±1% resistance precision for stable, repeatable temperature readings.
- Ready-to-Install: Comes with a 1-meter cable, making it a perfect replacement for broken or drifting stock sensors.
Applications
- Hot-End Monitoring: The primary sensor used in RepRap and Creality-style hotends to regulate nozzle temperature.
- Heated Bed Calibration: Essential for secondary temperature sensing to ensure even adhesion across the print surface.
- DIY Printer Builds: A fundamental electronic component for any custom FDM 3D printer project.
Package Includes
- 1 x 100k NTC Thermistor (1-meter cable)

Note: When replacing a thermistor, please ensure your printer’s firmware is set to the correct thermistor table (typically “Type 1” or “Type 11” in Marlin firmware) to ensure your temperature readings are accurate. For the best thermal contact, ensure the thermistor is securely fixed within the heater block cavity.
