Based on ceramic rods (insulators) and using both electroless and electrolytic plating, we supply low-resistance metal film resistor element bodies with excellent heat resistance, as well as plated element bodies for fuse resistors with excellent fusing characteristics.
At the same resistance value, our film thickness tends to be thinner than that of other manufacturers, with no loss of film strength. The film is also well matched to cutters, which reduces damage to both the cutter and the film.
