NTC thermistor and portable flashlight.NSP Type Power Thermistor

　　Since its formation in the late 1960s, flashlights have become an essential handheld lighting tool for every household. In daily life, people often need to use flashlights when encountering unexpected situations, such as car repairs, outdoor lighting, power outages, etc. With the continuous progress of technology, flashlights are also developing towards portability, small size, rechargeable, and multifunctional, resulting in the emergence of popular portable flashlights on the market. In order to prevent the motherboard from burning out due to excessive temperature during the operation of portable flashlights, manufacturers will install an NTC thermistor as a component for temperature monitoring and control.

　　A portable flashlight includes a shell, lens, lamp beads, battery, and printed circuit board. Among them, the miniature insulated lead NTC thermistor is installed on the printed circuit board, protecting the circuit while playing a role in temperature monitoring and control.

　　With the increasing demand for convenience in daily life, portable flashlights have been widely used in daily emergencies, car repairs, outdoor camping, outdoor construction, equipment maintenance, warehouse rooms, and other scenarios that require work or activities in low light conditions. Multifunctionality has also become one of the selling points of portable flashlights on the market. In addition to the common light adjustment function, portable flashlights also have functions such as SOS emergency, waterproof, and power bank.
