These Fusible Resistors contain both functions as being resistor in normal condition and turned into fuse while abnormal current comes in. The FR series Fusible Metal Film Resistors are manufactured by high vacuum sputtering deposit metal film on high thermal conductivity and specific gravity ceramic rods, and are coated with multilayers of green color flameproof lacquer.
