The SMD0603L-150-6V is a compact surface-mount polymeric PTC resettable fuse designed for dependable overcurrent protection in low-voltage electronic applications. With a 0603L footprint, 1.5A hold current and 6V maximum operating voltage, it rapidly shifts to a high-resistance state during fault conditions and automatically resets after the fault is removed. Its fast response, stable electrical performance and RoHS-compliant construction make it ideal for consumer electronics, portable devices and space-constrained PCB designs.
