2024-06-16 07:19:01, What Are PTC Resettable Fuses and How Do They Work?
What is a PTC Resettable Fuse? A PTC resettable fuse is an electronic component designed to protect circuits from overcurrent conditions. PTC stands for Positive Temperature Coefficient. Unlike traditional fuses that permanently break the circuit when overloaded, PTC resettable fuses temporarily open the circuit and then reset automatically.
