Bourns MF-R005-2 is a resettable fuse, also known as a PTC (Positive Temperature Coefficient) fuse, designed to protect circuits from overcurrent conditions. When an overcurrent event occurs, the fuse's resistance increases, limiting the current flow and preventing damage to the circuit. Once the fault is removed, the fuse automatically resets, restoring circuit functionality. These fuses are commonly used in computers, peripherals, and general electronics applications where reliable and automatic overcurrent protection is required. They are RoHS compliant and halogen free, meeting environmental standards. Available in various models with different voltage and current ratings, the MF-R series provides a versatile solution for circuit protection needs.
