Since taking shape in the late 1960s, flashlights have become a must-have handheld lighting tool in every household. In daily life, people often need to use a flashlight when encountering emergencies, such as car maintenance, outdoor lighting, power outages, etc. With the continuous advancement of technology, flashlights are also developing in the direction of being portable, small, rechargeable, and multi-functional, resulting in hot-selling portable flashlights on the market. In order to prevent the motherboard from burning due to excessive temperature during the working process of the portable flashlight, manufacturers will install an NTC thermistor as a component for temperature monitoring and temperature control.
The portable flashlight includes a casing, a lens, a lamp bead, a battery, and a printed circuit board. Among them, the miniature insulated lead NTC thermistor is installed on the printed circuit board, which protects the circuit and plays the role of temperature monitoring and temperature control.
