PTC Resettable Fuses
Positive Temperature Coefficient (PTC) Resettable Fuses deliver overcurrent protection for applications from -40°C to +85°C. Available in both radial leaded and SMD packages, they ensure accurate, efficient performance with quick trip times and high operating voltage capabilities which makes them best suited for high-density and high-power PCB applications.
