Fusible Resistors - FRN, FKN, FSQ Series

fusible,resistors

FRN, FKN, and FSQ Series are designed to act as an ordinary resistor under normal circuit conditions, and as a fuse under fault conditions. It is specially spiraled to provide the fusible function with flame retardant coating. Applications are widely used in constant voltage designed, overload protection, applicable for battery chargers, TV sets, cordless phones, and PC/CPU coolers. Token provides metal/carbon film (FRN), wirewound (FKN), and cement type (FSQ).
