This type named as Resettable Fuse PPTC DIP JK16 Series is widely used,computers&peripherals,toys,general electronics,any USB application,etc.
The polymer PTC polymer resettable fuse has the characteristics of fast response, instant protection, and automatic recovery. It can be installed once and used repeatedly. According to the needs of use, the product has many types to meet the needs of different circuit environments, and can be adapted to use under a variety of different environmental conditions, such as temperature conditions, voltage conditions, current conditions, and so on.
The main advantages of polymer PPTC are: the zero-temperature resistance at room temperature can be made small, high-current products have only a few milliohms, the power consumption on the road is small, can be ignored, and the volume is relatively small.
Can be connected in series in the vulnerable circuit for overcurrent protection and temperature fuse. The resistance value changes quickly. In the order of several ms, the heat capacity is small. The recovery time is short.
