What is PTC Fuses?
PTC Fuses are resettable overcurrent protection devices leveraging Positive Temperature Coefficient thermistors. Initially low resistance, they rapidly increase resistance when excessive current causes self heating beyond a critical temperature, effectively limiting current flow. This trip state is maintained until the fault is cleared and the device cools, returning to its low resistance state. Their key advantage is the ability to reset automatically or manually after a fault, unlike traditional one time fuses. PTC Fuses are widely used in electronics, telecommunications, automotive, and industrial applications to protect circuits from overcurrents without requiring replacement, enhancing reliability and reducing maintenance.
