NTC Thermistor And Portable WiFi
2022/11/01 03:11:34

With the popularity of electronic products such as laptop and smartphone, portable WiFi has been introduced to avoid poor communication signals encountered by people when working on the go and traveling across borders. In order to make it easier for users to use the Internet anytime, anywhere, most of the portable WiFi on the market is rechargeable. In order to avoid overcharging/overdischarging during the charging process of portable WiFi, NTC thermistor is generally selected for temperature monitoring and temperature control.

As a mobile signal conversion device, portable WiFi can serve multiple wireless terminals at the same time. If it is overheated during work, it will affect the use of the user, or even lead to the damage of the portable WiFi and the wireless terminal. Therefore, as the key to temperature control, the role of NTC thermistor cannot be underestimated. Taking advantage of the characteristics that the resistance value of NTC thermistor decreases with the increase of temperature, real-time temperature monitoring can be carried out on the portable WiFi to ensure that its working temperature is normal.

Considering the easy carrying, small size, and light weight of portable WiFi, the selection of NTC thermistor is also very knowledgeable. As a preferred, most manufacturers will choose the IT series miniature insulated lead NTC thermistor produced by EXSENSE Electronics Technology Co., Ltd., which has high temperature measurement accuracy (it can up to ±0.5%), which can meet the real-time temperature monitoring requirements of portable WiFi; Its head size is small, the leads can be bent, and it occupies a small mounting position on the PCB board. In order to improve the integration and reduce costs of portable WiFi better, EXSENSE Electronics now launches a new CT series SMD type NTC thermistor, which uses ultra-high isostatic pressing combined with ceramic slicing process to improve the compactness of thermistor and achieve long-term high reliability. In addition, SMD type NTC thermistor are suitable for surface mounting, which can meet the automation assembly needs of portable WiFi.
