The Glass-Sealed 100K Ohm NTC 3950 Thermistor (Pack of 2) is a high-precision temperature sensing component designed for accurate and stable thermal measurements in electronics, robotics, and embedded systems. Featuring a negative temperature coefficient (NTC), the resistance decreases predictably as temperature increases, making it ideal for precise analog temperature monitoring.

With a 100KΩ resistance at 25°C and a 3950K beta value, this thermistor is widely compatible with popular temperature-measurement circuits and firmware used in Arduino, Raspberry Pi (with ADC), ESP32, AVR, PIC, 8051, and other microcontroller platforms. The ±1% tolerance ensures improved accuracy compared to standard thermistors, making it suitable for applications requiring reliable temperature control.

The glass-sealed construction provides excellent protection against moisture, oxidation, and environmental stress, ensuring long-term stability and fast thermal response. These thermistors are commonly used in 3D printer hot-end temperature sensing, battery packs, power supplies, HVAC systems, motor temperature monitoring, and over-temperature protection circuits.

Supplied in a pack of 2, this product is perfect for DIY enthusiasts, students, educators, and professional developers working on prototyping, repair, or replacement tasks.
