DIP Positive Thermal Coefficent PPTC Resettable Fuse RL30 Series

Description of DIP Positive Thermal Coefficent PPTC Resettable Fuse RL30 Series

Positive Thermal Coefficient devices(PTC), also called PPTC resettable fuses, PolySwitch, polymer positive temperature thermistor, self recovery fuse, provide over-current protection for electrical and electronic devices. They function using conducting strips of metal imbedded inside polymers. Under normal conditions, the devices resistance is near zero, but over-current conditions will heat the PTC and expand the polymer, increasing the impedance. When current returns to normal, the components cool down, returning to their original shape and very low levels of resistance.
