A Thermal Protector is a device designed to provide heating protection in batteries, motors, and similar components. It's a crucial safety feature in various electronic products.
This protector activates when the temperature of components such as batteries or motors rises abnormally, automatically controlling the current to suppress further temperature increases. Its role is vital in preventing the deterioration or damage of motors, and in avoiding ignition or overheating of batteries due to high temperatures.
Thermal Protectors are commonly used in devices like laptops, tablets, smartphones, and digital cameras. They are also essential in lithium-ion and nickel-metal hydride batteries, which are frequently used in medical devices and wireless communication equipment.
