(figure for PPTC self recovery fuse typical application circuit)

Characteristics of PPTC self recovery fuse
It is sensitive to current and temperature, and the resistance increases with the increase of temperature and current.
The response speed of PPTC self recovery fuse is slow, which is usually tens of milliseconds or even second level, which is related to the current of PPTC self recovery fuse.
It has self recovery characteristics and can be used repeatedly in circuit within its rated range.
The PPTC self recovery fuse is low resistance in the normal working state of the circuit, and has little effect on the circuit.
In application, the PPTC self recovery fuse is connected in the circuit.
Our PPTC self recovery fuse product maintains a current of 30mA~14A and the maximum voltage is 5V~600V.
