300C glass bead ntc thermistor, suitable for 3D printer

Product Description   Glass encapsulated thermistors provide a low cost option for applications that require superior stability and high temperature operation. The thermistors are glass encapsulated to allow for operation in a wide array of environments including high humidity and rapid thermal cycling. The small size allows the sensor to react quickly to small temperature changes. Contact the factory for specific design or application information or the availability of options. FEATURES High reliability, stability, high sensitivity Wide range of resistance: 0.5~1000KΩ Usable in high-temperature and high-moisture environments due to the glass wrapping Small, light, firm structure, convenient automatic installation on PCB Rapid response time Operating Temp. -40+300 C Lead wire: dumet wires     Product Uses   Temperature compensation and detection for Office automation facilities (e.g. Copiers, printers etc.) Household appliances ( air conditioners, microwave ovens, electric fans, electric heaters) Industrial, medical, environmental protection, weather and food processing equipment Liquid level display and flow water measurement  Apparatus coils, integrated circuits, quartz crystal oscillators and thermocouples.
