Will thermistor burn when the temperature is too high? This is a very common problem. Some people think that the excessive temperature of thermistor may be caused by heat.
1: Will thermistor burn when the temperature is too high?
Will thermistor burn when the temperature is too high? This is a controversial issue. The common reasons are as follows: 1. Aging wires. If the wire is old, heat is easily transferred to the thermistor; 2. The cables are improperly connected. The electronic components distributor believes that the thermistor was not properly plugged into the circuit prior to connection, which causes a failure. 3. The input voltage is unstable. The unstable input voltage is also one of the causes of overheating of thermistor. 4. Too few radiators. High heat may damage or disable the thermistor. In order to avoid excessive heating of thermistor, it is best to keep the wire dry to prevent breaking or loosening; 5. The ambient humidity is high. Moist air contains more water vapor, at this time should pay attention to moisture-proof measures, such as pad, humidification, in order to reduce the impact of moisture on the thermistor.
2: What are the common reasons?
There are many reasons for thermistor overheating, and the main ones are as follows :1. The supply voltage is unstable. If the ambient temperature is too high or the ambient humidity of the equipment is too high, the thermistor will overheat and burn out; 2. Poor circuit design. If the circuit board has conductive copper wire, conductor and insulating layer and other foreign body contact poor will also cause heating; 3. The quality of the connector is not good. If the connection wire is improper, such as the connection point contact is not good, etc., may produce fever phenomenon; 4. Interference factors of electronic circuit. There are a lot of interference signals in the electronic circuit, they are suppressed by grounding measures, so that the circuit can not work normally; 5. Poor protection capacitor performance. When the capacitor failure, the thermistor will be damaged by impact and overheating;
3: How to prevent thermistor overheating?
Will thermistor burn when the temperature is too high? What are the common reasons? How do you prevent a thermistor from overheating? 1. First, make sure you are exposed to high temperatures. If you place thermistors in a relatively high place, they may ignite. 2. Secondly, do not put the heating element directly on the flammable material. Doing so will only add heat and cause unnecessary and dangerous accidents. 3. Finally, keep away from heat sources and strong magnetic fields. These factors can lead to thermistor failure or even combustion explosion. Therefore, be careful to avoid contact with hot objects or near your workplace.
However, others disagree with this view. They believe that thermistor temperature is too high for some reason. We're not sure which view is the most accurate.
