Frequently Asked Questions
Q: What resistance value should I choose – 5K, 10K, 50K, or 100K Ohm?
A: The most commonly used value for general-purpose temperature sensing (such as in 3D printers and Arduino projects) is the 10K Ohm NTC MF58 thermistor. The 5K variant suits lower-impedance circuits, while 50K and 100K are better suited for high-impedance input stages or low-power applications. Always match the thermistor resistance to your circuit's pull-up resistor and ADC range for best accuracy.
Q: Are these NTC MF58 thermistors compatible with Arduino and Raspberry Pi?
A: Yes! The MF58 through-hole NTC thermistors are widely compatible with Arduino, Raspberry Pi, ESP32, and other microcontroller platforms. Simply connect them in a voltage divider circuit with a matching resistor, read the analog voltage, and use the B-value (3950) in the Steinhart-Hart or Beta equation to calculate temperature.
Q: What does "glass sealed" mean and why does it matter?
A: Glass sealed means the NTC sensing element is encapsulated in a small glass bead or tube, protecting it from humidity, dust, and oxidation. This construction improves long-term stability and makes the thermistor more resilient in slightly harsh or variable environments compared to resin-coated alternatives.
Q: Can I use these thermistors in a 3D printer?
A: Yes. The NTC MF58 3950B 100K Ohm thermistor is one of the most popular choices for 3D printer hotend and heated bed temperature sensing. When configuring your firmware (e.g. Marlin), select thermistor type 11 or the appropriate MF58 3950 profile for accurate readings.
