The Littelfuse FRN-R-1 Time Delay Thermal Fuse is a 1 Amp thermal protection device in the FuseTron FRN-R-1 family. As a time-delay thermal fuse, it opens the circuit after a thermal event with an intentional delay to tolerate short heat spikes. This Littelfuse component provides over-temperature protection by interrupting current when the thermal threshold is reached, helping prevent damage from overheating.
