The miniature insulated lead NTC thermistor produced by EXSENSE Electronic Technology Co., Ltd. is widely used in cell phone battery, wireless charging, mobile power, electronic thermometer, etc. Due to its small epoxy head, high sensitivity and high accuracy (accuracy can up to ±0.5%, ±1%, ±2%, ±3%).
Nowadays, smart phone has become one of the daily necessities for everyone. And because of the fever and hot from excessive use of mobile phone, or because of the external temperature plummeting, resulting in phenomenon of suspended operation, automatic shutdown of cell phone, happen from time to time. So, we can not help but wonder, how can a phone tell if it's too hot or too cold to trigger a self-protection program? Let EXSENSE Electronics tells you that this is all due to the addition of miniature insulated lead NTC thermistor.
On the outside of the cell phone battery, we can see several contacts, in addition to the two contacts representing the positive and negative poles of the battery, the rest of the contacts are responsible for temperature monitoring of mobile phone, which will use NTC thermistor. Due to the resistance value of NTC thermistor varies with temperature, during the operation of cell phone batteries, through the resistance value of thermistor changes to determine the rise and fall of temperature, and feedback the information to the cell phone self-protection program, effectively prevent damage of cell phone as a result of extreme temperature change battery, greatly improved the safety of user to use a cell phone. Miniature insulated lead NTC thermistor plays the role of temperature monitoring and temperature control in cell phone battery, which can effectively prevent damage to cell phone battery and prolong the service life of cell phone battery.
