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. | ||||||||
