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. Note: The Music sync function works in LAN mode only and requires access to the smartphone microphone. Color availability and model functionality may vary slightly based on region and stock.
