Positive Thermal Coefficent PTC Resettable Fuse

Self-recovery fuse is a kind of over-current protection device. It is made of high-molecular organic polymer under high pressure, high temperature and reaction conditions, after adding conductive particle materials, and processed through a special process. It has an automatic recovery function and works on the principle of energy dynamic balance.

Positive Thermal Coefficient Device (PTC), provides overcurrent protection for electrical and electronic devices. Their function is to use conductive metal strips embedded in the polymer. Under normal conditions, the resistance of the device is close to zero, but in the case of overcurrent, the PTC will be heated, causing the polymer to expand and increasing impedance. When the current returns to normal, the component will cool down and return to its original shape and extremely low resistance level.
