The SMD2920-300-16V is a surface-mount polymeric PTC resettable fuse designed for reliable overcurrent protection in low-voltage electronic systems. Featuring a 2920 footprint, 3.0A hold current and 16V maximum operating voltage, it automatically switches to a high-resistance state during fault conditions and resets once the fault is removed. With robust surge handling capability and RoHS-compliant construction, it is ideal for power input protection in industrial electronics, power adapters and consumer devices.
