The RF30-160F is a PTC polymer-based fuse manufactured by AUPO. It has a current rating of 1.6A. The fuse is designed to protect circuits against an overcurrent condition. It utilizes a temperature-sensitive polymeric material to detect abnormal current events and limit their effects. The PTC polymer fuse has a low temperature coefficient, providing protection from short circuits, overvoltage, and other fault conditions. It has a fastacting response time and is RoHS compliant. The RF30-160F is generally used in consumer electronic products such as smartphones, tablets, and other small electronic devices.
