Metal Film Precision Resistors (OMF)

The Metal Film Precision Resistors (OMF) that we deal in is designed making use of sophisticated machines and latest techniques. As a result, they come with high tensile strength and longer functional life.
Highlights :

• A homogeneous film of nichrome alloy is sputtered deposited on 70% to 85% alumina ceramic and conditioned to achieve the desired temperature coefficient
• Nickel plated caps are firmly pressed on the metalized rods
• A special laser machine is used to achieve the highly precise resistance tolerance by cutting a helical groove in the film layer
• Tin coated electrolytic copper wire are spot welded to the center of the termination caps
• The resistor is coated with special epoxy or flameproof epoxy for electrical, mechanical and climatic protection, color codes are applied with respect to designated value on coated resistor
• All resistors are subjected to testing before final taping process

Features :

• Wide Range of Resistors
• Low TCR up to 5 ppm/C
• Low Tolerances up to ± 0.01%
• Pulse withstanding design available
• Flame proof coating available
• RoHS Compliant

• Custom Built Design and values available
