This extremely small surface mount voltage divider made of

Bulk Metal

ultimate in ratio stability. Additionally Bulk Metal

extremely low absolute temperature coefficient of resistance

so the temperature differential caused by power unbalances

associated with large ratios will not adversely affect the tracking

specification. The absence of noise generation by the resistor

make it the ultimate component.
