AMPFORT Electronics currently has conventional wire diameters of Ø0.18mm, Ø0.3mm and different wire diameter specifications enameled wire epoxy package, conventional resistance value 50K, 10K. Accuracy 1% 2% 3%, etc. B value 3950, 3435, 3380, etc. , The head diameter is 1.2mm, 1.3MM, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, etc., in order to meet different needs, it can be customized according to customer requirements.
Application of enameled wire NTC thermistor in fast charging mobile power
With the increasing capacity of mobile phone batteries, people have higher and higher requirements for battery charging speed. Fast charging should be used in this context. Others include fast charging mobile power supplies. The mobile power supply has higher requirements for battery temperature control and protection due to its personal use characteristics. An NTC thermistor with high stability is particularly important.
The picture below shows a fast charging mobile power bank of Xiaomi brand. We use this product to see how the MF52B enameled wire NTC thermistor is used in practice.
The lead wire of the NTC thermistor is fixed to the designated port of the control board by welding, and the key NTC thermistor head is directly fixed between the two cells with tape, so that the direct NTC can detect the source faster The temperature change of the battery board makes the mobile power more safer during use.
Application of enameled wire NTC thermistor in Xiaomi wireless power bank
As with the protection of moving over the power supply, our MF52B type enameled wire thermistor is still selected for the temperature protection of wireless charging, because the characteristics of this NTC are really suitable for charging needs.
In use, the same two leads of NTC are respectively welded to the NTC pins of the wireless charging control board, and then the leads are drawn to the middle of the coil on the front and fixed with tape. It is very convenient to use and works well. Detect the heating of the entire coil.
Ps: The length of the thermistor lead can be customized according to the wireless charging size.
