FUSIBLE RESISTORS

Fusible Resistors

FRN, FKN, FSQ

Tokenchina's Fusible Resistor FRN, FKN, and FSQ Series are precisely controlled resistance, stable and accurate designed for dual purpose that performs as a metal/carbon film resistor (FRN), wirewound resistor (FRN), or cement ceramic housed resistor (FSQ) and also as a fuse. Fuse resistor is ideal for power circuit overload protection and allows precise fusing point and time log.


Tokenchina full line resistors meet RoHS compliant. Detailed specifications, both mechanical and electrical, are maintained for many popular designs on our website, or by contacting our sales representative.
