What is a metal foil resistor?
Metal foil resistors offer unmatched performance for the highest precision applications, without compromising on accuracy, stability or speed. They are constructed by adhering a metal alloy foil, usually nickel/chromium (Nichrome) with some additives,to a ceramic base. Typically this foil is a few microns thick.
Is a lower TCR better?
This also applies to a resistor in that the lower TCR will result in a more stable measurement across temperature, which may be caused by applied power (causing the resistance element temperature to increase) or ambient environment.
What is bulk metal foil resistor?
• The Bulk Metal Foil resistor is based on a special concept where. a proprietary bulk metal cold-rolled Foil is cemented to a ceramic substrate. • It is then photo-etched into a resistive pattern and trimmed. using a ladder-rung technique to within very tight tolerances of the nominal value.
