POSITIVE THERMAL COEFFICIENT(PTC)

Description

Positive Thermal Coefficient devices(PTC),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.
