The NANOSMDC110F-02 is a surface-mount resettable fuse, also known as a Polymeric Positive Temperature Coefficient (PPTC) device, manufactured by Littelfuse. It is designed to protect electronic circuits from overcurrent conditions. When an overcurrent event occurs, the device's resistance increases sharply, limiting the current flow and protecting downstream components. Once the fault is cleared and power is removed, the device cools down and its resistance returns to a low level, allowing normal circuit operation to resume.
