Hair curler is a kind of handheld electronic product used for curling hair. Its main components are a handle and a heating roller. The hair curler has a built-in heating device, which uses NTC thermistor to measure the temperature and feeds it back to the temperature control circuit board to monitor the heating of the heating wire, so that the heating drum heats up quickly, and the heating is uniform and stable.
NTC thermistor is an important part of temperature measurement and control in hair curlers. Single-ended glass-sealed NTC thermistor can meet the high temperature resistance and fast induction requirements of hair curlers. It has a smaller size, the glass head size after packaging has three sizes of 0.8mm/1.3mm/2.3mm, the lead wire uses Dumet wire, and the chip selects the characteristics of lower resistance and higher B value. And the leads are on the two sides of the chip, and the pins are not on the same side, which is more convenient to use. When lower power is applied to the glass-sealed thermistor, the glass-sealed thermistor can heat up to 180℃～200℃ in a short time, and it is suitable for high temperature occasions. Single-ended glass-encapsulated thermistor products have the characteristics of stable signal transmission, high temperature resistance, high accuracy, and high range. They are used for high temperature waterproof temperature measurement and detection.
