Ideal for high-density circuit boards including mobile devices, USB ports, dishwashing machines, and other space-constrained applications requiring reliable overcurrent protection with automatic reset capability.
Unlike traditional fuses that require replacement after tripping, PTC resettable fuses automatically return to low-resistance state once the fault condition is removed. The polymer-conductive material composite structure provides self-regulating protection by increasing impedance during overcurrent events and resetting automatically when normal conditions resume.
