are tested for value and tolerance.
Key Features
I
Precision metal film resistors
with tolerance to 0.1% and
temperature coefficients to
15ppm.
I
Metal film resistors have
excellent stability under load
and severe environmental
conditions. They exhibit very
low noise current and voltage
coefficients. Precision metal
film resistors are particularly
