1. Nominal resistance Rc: Generally refers to the actual resistance value of the Cool Shot Hair Dryer Factory in China when the ambient temperature is 25℃. ② Actual resistance RT: The resistance value measured under certain temperature conditions.

2. Material constant: It is a parameter that describes the physical properties of the materials in the cool shot hair dryer factory in China, and it is also a thermal sensitivity indicator. The larger the B value, the higher the sensitivity of the cool shot hair dryer factory in China. It should be noted that in actual operation, the B value is not a constant but increases slightly with the rise in temperature.

3. Resistance Temperature Coefficient αT: It represents the rate of resistance change per 1°C of temperature variation, with the unit being %/°C.

4. Time constant τ: The cool shot hair dryer factory China device has thermal inertia. The time constant is a parameter that describes the thermal inertia of the cool shot hair dryer factory China device. It is defined as the time required for the temperature of the cool shot hair dryer factory China device to change by 63.2% of the difference between two specific temperatures when the ambient temperature suddenly changes from one specific temperature to another specific temperature, under the condition of no power consumption. The smaller the τ, the smaller the thermal inertia of the cool shot hair dryer factory China device.

5. Rated Power PM: Under the specified technical conditions, this Cool Shot Hair Dryer Factory China appliance is permitted to dissipate power during long-term continuous operation. During actual use, the rated power must not be exceeded. If the ambient temperature of the Cool Shot Hair Dryer Factory China appliance exceeds 25℃, the load should be reduced accordingly.

6. Rated working current IM: The nominal current value specified for the cool shot hair dryer in its operating state.

7. Measuring power Pc: Under the specified ambient temperature, the power consumed by the Cool Shot hair dryer factory China when the body is heated by the test current and the resistance change does not exceed 0.1% is measured.

8. Voltage: For the NTCcool shot hair dryer factory China product, it refers to the maximum continuous DC voltage that can be applied to the cool shot hair dryer factory China without causing thermal runaway under the specified environmental temperature; for the PTCcool shot hair dryer factory China product, it refers to the DC voltage that can be continuously applied to the cool shot hair dryer factory China and ensure its normal operation within the PTC characteristic range under the specified environmental temperature and still air conditions. ⑩ Operating Temperature Tmax: The maximum temperature that the cool shot hair dryer factory China can withstand for long-term continuous operation under the specified technical conditions.

9. Switching temperature tb: The temperature at which the resistance value of the PTC cool-shot hair dryer factory in China begins to increase sharply.

10. Dissipation Coefficient H: The power dissipated by the cool shot hair dryer factory in China when the temperature increases by 1℃, measured in mW/℃.
