PDF File Data Spec Ultra Miniature Metal Film Resistor - UMR Series

INTRODUCTION
The UMR Series flame-proof type miniature Metal Film Resistors are manufactured by vacuum depose it metal film on
high thermal conductivity and specific gravity Rosenthal ceramic or same grade Japans 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 significantly 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.
