Description of NTC Thermistor 100K 3950 Sensor

The NTC Thermistor 100K 3950 is a widely used temperature sensor, especially trusted in 3D printing and high-precision electronics. It features a resistance of 100KΩ at 25°C, ensuring accurate readings in temperature-sensitive applications. The B value of 3950K ± 1% reflects its responsiveness to temperature changes — making it a top choice for environments where thermal consistency is key.

Built to withstand extreme conditions, the sensor operates reliably from -40°C to +250°C, covering a broad temperature spectrum. Its ≤ 10-second thermal response time allows it to adapt quickly to environmental shifts, which is crucial for hotend and heated bed monitoring in 3D printers.

Engineered with ≥50MΩ insulation resistance (tested with DC500V), the sensor ensures safe integration into both consumer-level and industrial systems, preventing signal interference and component damage.

This thermistor is not only used in 3D printers, but also in HVAC systems, smart devices, and embedded circuits where maintaining proper temperature is vital for functionality and safety. With its long-term reliability and compact build, it's a practical solution for thermal control in both hobby and professional setups.

NTC Thermistor 100K 3950 Sensor – Frequently Asked Questions


What is an NTC Thermistor 100K 3950?
The NTC Thermistor 100K 3950 is a temperature sensor with a resistance of 100KΩ at 25°C. It features a B value of 3950K, providing high sensitivity and accuracy for temperature monitoring in various electronic applications.
What is the B value in a thermistor?
The B value, in this case 3950K ±1%, indicates how the resistance of the thermistor changes about temperature. A higher B value means the sensor is more responsive to changes, which is critical for precise thermal management.
What is the operating temperature range of the 100K 3950 thermistor?
This thermistor can function reliably within a wide range of -40°C to +250°C, making it suitable for demanding environments like heated components in 3D printers and industrial machines.
Is the 100K 3950 thermistor safe for industrial use?
Yes, the sensor has an insulation resistance of ≥50MΩ when tested with DC500V, ensuring safe performance and minimizing electrical interference in both consumer-grade and industrial systems.
How fast does the 100K 3950 thermistor respond to temperature changes?
It has a thermal response time of 10 seconds or less in still air, allowing for rapid detection of temperature shifts. This makes it highly effective in real-time temperature-sensitive applications.
What are the main uses of the 100K 3950 thermistor?
It is widely used in 3D printer hotends and heated beds, HVAC systems, environmental monitoring devices, industrial thermal controls, and embedded electronics for temperature regulation.
What’s included in the package?
The package typically includes one NTC Thermistor 100K 3950 Sensor.
