INTRODUCTION
The FMF Series flame-proof type miniature Metal Film Resistors are manufactured by vacuum depos it metal film on high thermal conductivity and specific gravity Rosenthal ceramic or same grade Japaness rods. The both ends of ceramic are coated with precision mixed metals which help to prevent against noise, and to provide low TCR and low Tol precision resistors the can meet MIL and JIS requirement.
Utilizing a 95~98% of AI ceramic cores and combined a special cutting technology inside, this resulting superior resistors give excellent heat dissipation, stable performance and dignificantly up-grade the power rating.
This specially designed resistors are widely used by the industries of communication devices, meters, high-class, audio equipments and precision military defending facilities as well.
