With the popularity of a variety of consumer electronics, all kinds of charging accessories to get rid of the stale and bring forth the new, for its escort. In recent years, wireless charging technology has gradually become a part of People's Daily life due to its advantages of convenient operation, high safety, good compatibility and wide application range. The miniature insulated lead NTC thermistor produced by EXSENSE Electronics Technology Co., Ltd. Has the characteristics of high precision, high sensitivity, small epoxy coating head, plays a role of temperature monitoring and temperature control in the wireless charger, to ensure the safety of the wireless charging process.

Wireless chargers generally include housings, wireless charging coils, PCB boards, cell, and temperature-measuring NTC thermistors. The cell in the wireless charger is protected by foam cotton, the wireless charging coil and the miniature insulated lead NTC thermistor for temperature control are placed in the center. The wireless charging circuit board is screwed and the shield case is covered on the circuit. The front of the PCB board is electro-glued, the charging contacts are welded to the position of the previous charge indicator, which is on the right side of the circuit board, and the middle area on the back is shielded. After the front and back of the PCB board circuit observation can be found that the wireless charger using a master chip to control, through the synchronous lift voltage conversion voltage to achieve USB input/output and wireless charge output design architecture.

Inside the wireless charger, there is a plastic board between the circuit boards for isolation, the cell is covered with foam cotton protection, in addition, there is a thermal conduction sticker on the body housing to help heat dissipation. It built-in mobile phone detection, no need to press the key to activate the mobile power for wireless charging of the mobile phone. Wireless charger can also support wireless fast charging, for users who are still looking for charging accessories or considering buying one, it is a good choice, very practical.

Wireless chargers with miniature insulated lead NTC thermistor are added to effectively dissipate heat while working to ensure the safety of the charging process. Thermistors can also take advantage of their temperature monitoring function to avoid accidents caused by excessive temperature.
