An NTC (Negative Temperature Coefficient) thermistor with SM Terminal is a type of
resistor whose resistance decreases as the temperature increases. The
100k Beta 3950 model is widely used in temperature measurement
applications, such as in 3D printers and Arduino projects.
This sensor measures the temperature in a heating block of an extruder
in a 3D printer and it is used to control the extrusion temperature of
the filament.
Main Features:
- Resistance at 25°C: 100kΩ
- Beta Coefficient: 3950K (indicates the relationship between resistance and temperature)
- Measurement Range: -40°C to 320°C
Approximately 3mm diameter and 15mm length;
Cable Length: Generally 1 meter, with Teflon insulation for greater durability.
Common Applications:
3D Printers: Used to monitor and control the temperature of the heated bed and hotend.
Arduino Projects: Ideal for measuring ambient temperature or specific components.
Compatible with the following blocks, for example:
