Roma Power Bank Temperature Protection NTC Thermistor.Photosensitive sensor

　　Starting from this year, the newly launched wireless charging banks of Romance have been incorporating our company's enameled NTC thermistors into mobile power supplies. Since then, the problem of Romance charging banks lacking temperature protection, which has been criticized by many netizens, has finally been eliminated. The NTC temperature probe (NTC thermistor) is fixed to the lithium battery board with silicone, which allows the NTC probe to quickly reflect data and disconnect in case of abnormal overheating of the battery. This can truly provide protection in the event of overcharging of the power bank. It is reported that all power banks that will be launched in the later stage will add NTC temperature protection to eliminate safety hazards.

　　First, let's introduce the parameters of this NTC thermistor. On the power bank, the vast majority of manufacturers have chosen this MF52B enameled wire NTC thermistor. It has a fast temperature response speed, a small head diameter, and can be directly arranged in a narrow space. The length of the wire can be customized according to the size of the power bank.

　　MF52B - Parameters of NTC thermistor for enameled wire:

　　Resistance value: R25=10K Ω/100K Ω

　　Accuracy: 1%, 2%, 3%, 5%

　　B value: 3380k/3435k/3950k

　　Temperature range: -40~125 ℃

　　Line length: 40-70mm (customizable)
