Note: Foil shown in black, etched spaces in white
To acquire a precision resistance value, the Bulk Metal® Foil
chip is trimmed by selectively removing built-in “shorting bars.”
To increase the resistance in known increments, marked areas
are cut, producing progressively smaller increases in resistance.
This method reduces the effect of “hot spots” and improves the
long term stability of the Vishay Foil chips.
