NTC thermistor for heating the coaster.20mm glass cap Photoresistor

　　In cold times, people are generally willing to choose hot water to drive out the cold, while the water temperature of ordinary glass or porcelain cup will drop quickly after being put into hot water, and even the heat preservation cup cannot always meet the heat preservation effect. In addition, the taste of tea and coffee will be greatly affected when they become cold.

　　The heating coaster is a thermostatic heating coaster, which can easily heat the water cup, prevent the water in the cup from becoming cold, and can automatically open or close according to the placement of the water cup, thus saving electric energy.

　　The heating coaster is usually composed of the heating panel, the fuselage, the PCBA board and the pressure switch set at the bottom of the fuselage. The NTC thermistor most commonly used to heat the coaster is the NTC enamelled wire thermistor with small head diameter.

　　Enamelled wire NTC thermistor is a small, high-precision insulating polymer coating of chip and enameled copper wire, coated with epoxy resin, and NTC interchangeable thermistor with bare tinned enameled copper lead.

　　With high reliability, stability and sensitivity, it is easy to apply to the heating coaster. In addition, it has long-term stability and fast response time, which is the best choice for the heating coaster.

　　The conventional wire diameters of NTC enamelled wire thermistors produced by our company are 0.18mm, 0.3mm and epoxy encapsulation of enamelled wire with different wire diameters. The conventional resistance values are 50K, 10K. The accuracy is 1%, 2%, 3% and other B values are 3950, 3435, 3380, etc. The head diameters are 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, etc. To meet different needs, we can customize according to customer requirements.
