Points to note about the application requirements of single-ended glass-sealed NTC thermistors:
Single-end glass-sealed NTC temperature sensors are attributed to fine electronic accessories. After opening, please keep at room temperature or low temperature and keep it low. The parts of this product meet the ROHS environmental protection requirements (exemptions are excluded)
Single-ended NTC thermistor products are classified as current and voltage sensitive components. Please ensure that the connected circuit does not have large current or pulse or wave source current to avoid burnout.
