The TD250-1-5 with PTC Resettable Fuses RoHS manufactured by TLC is a thermally protected device designed to help protect electrical circuits from overcurrent. This resettable fuse features an internal PTC (positive temperature coefficient) that can detect an overcurrent and automatically stop the flow of electricity, even if the current is too low to trip a traditional fuse. The PTC Resettable Fuse will automatically reset once the current returns to an acceptable level. This device is RoHS compliant, which means it meets European environmental regulations for use in lead-free electronics. The TD250-1-5 is an industry-standard component, widely used in a variety of consumer electronics today.
