It is a commonly used 100K NTC temperature sensor compatible with RepRap-based 3D printing applications and DIY electronics projects. This thermistor features a high-sensitivity NTC thin-film design that provides fast and stable temperature response. With a measurement range of -40°C to 270°C and ±1% accuracy, it ensures reliable thermal control for maintaining consistent printing temperatures. The sensor comes pre-wired with high-temperature PTFE/Teflon insulated cable, providing excellent heat resistance and durability when installed near hot ends and heating elements. The compact glass-sealed thermistor body allows easy installation while maintaining stable performance during continuous operation. The NTC 3950 thermistor is widely used for monitoring extruder temperature, heated bed temperature and other thermal control applications. It is suitable for RepRap 3D printers, Arduino projects, temperature controllers, electronic equipment and industrial sensing applications. Review: Accurate Thermistor - this is a very good Thermistor. It is very well made. The resistance is accurate according to the datasheet of this. I have no complaints what so ever. Worth the cost. Review: Working fine - I have been using this for 1 month since my stock sensor was damaged. No problems yet, the cost is comparable to other similar products. Overall I have no issues with the item. ## Features - High Accuracy Temperature Sensor : 100KΩ NTC 3950 thermistor provides reliable temperature measurement with ±1% accuracy for precise 3D printer heating control - Wide Temperature Range : Supports temperature sensing from -40°C to 270°C, making it suitable for extruders, heated beds and high-temperature applications - Heat Resistant PTFE Wiring : Features pre-wired high-temperature Teflon insulated cable designed for safe operation near hot ends and heating components - Fast Response Performance : High sensitivity thermistor design provides quick thermal response with a time constant of less than 7 seconds for efficient temperature monitoring - 3D Printer Compatible Design : Commonly used with RepRap, Arduino-based 3D printers, extruder hotends, heated beds and DIY temperature control projects ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Robocraze | | Manufacturer | RoboCraze | | Country of Origin | China | | Model number | RC-A-41369 | | Number of Memory Sticks | 1 | | Item Weight | 30 g | | Product Dimensions | 4.8 x 9.9 x 13 cm; 30 g | | Item model number | RC-A-41369 | | Item Height | 13 Centimeters | | Item Width | 9.9 Centimeters | | Are batteries included? | No | ## Images ![Robocraze NTC 3950 100K Ohm Thermistor Temperature Sensor for 3D Printer | Pre-Wired PTFE Teflon Cable Temperature Probe for RepRap Extruder Heated Bed Hotend Arduino DIY Printing Projects - Image 1](https://m.media-amazon.com/images/I/51D+rz0YWLL.jpg) ![Robocraze NTC 3950 100K Ohm Thermistor Temperature Sensor for 3D Printer | Pre-Wired PTFE Teflon Cable Temperature Probe for RepRap Extruder Heated Bed Hotend Arduino DIY Printing Projects - Image 2](https://m.media-amazon.com/images/I/41zGymhbCAL.jpg) ![Robocraze NTC 3950 100K Ohm Thermistor Temperature Sensor for 3D Printer | Pre-Wired PTFE Teflon Cable Temperature Probe for RepRap Extruder Heated Bed Hotend Arduino DIY Printing Projects - Image 3](https://m.media-amazon.com/images/I/41of9o8fdtL.jpg) ![Robocraze NTC 3950 100K Ohm Thermistor Temperature Sensor for 3D Printer | Pre-Wired PTFE Teflon Cable Temperature Probe for RepRap Extruder Heated Bed Hotend Arduino DIY Printing Projects - Image 4](https://m.media-amazon.com/images/I/31s3jvI5VlS.jpg) ![Robocraze NTC 3950 100K Ohm Thermistor Temperature Sensor for 3D Printer | Pre-Wired PTFE Teflon Cable Temperature Probe for RepRap Extruder Heated Bed Hotend Arduino DIY Printing Projects - Image 5](https://m.media-amazon.com/images/I/41ZRwGy8nAS.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Accurate Thermistor *by Y***U on 27 September 2025* this is a very good Thermistor.
