Precautions for the use of NTC thermistors

　　1. Pay attention to the working temperature of the NTC thermistor.

　　Never use the NTC thermistor outside the operating temperature range. The operating temperature of φ5, φ7, φ9, and φ11 series is -40~+150℃; the operating temperature of φ13, φ15, and φ20 series is -40~+200℃.

　　2. Please pay attention to use NTC thermistor under the condition of rated power.

　　The maximum rated power of each specification is: φ5-0.7W, φ7-1.2W, φ9-1.9W, φ11-2.3W, φ13-3W, φ15-3.5W, φ20-4W.

　　3. Precautions for use in high temperature and high humidity environment.

　　If the thermistor needs to be used in a high temperature and high humidity environment, a sheath type thermistor should be used, and the closed part of the protective sheath should be exposed to the environment (water, moisture), and the opening part of the sheath will not directly touch water and steam.

　　4, can not be used for harmful gas, liquid environment.

　　Do not use it in a corrosive gas environment or in an environment where it will come into contact with electrolytes, salt water, acids, alkalis, and organic solvents.

　　5. Protect the wires.

　　Do not overstretch and bend the wires, and do not apply excessive vibration, shock and pressure.

　　6. Keep away from heat-generating electronic components.

　　Avoid installing electronic components that are prone to heat around the power NTC thermistor. It is recommended to use products with higher leads on the upper part of the bent feet, and use the NTC thermistor to be higher than other components on the circuit board, so as not to affect the normal operation of other components due to heat.
