The typical pattern and trimming illustrations show that the
V5X5P resistor has 16 trimming points, the V15X5P has 20
and the V15X10P has 21. These trimming points are
arranged around the chip periphery and are clearly indicated.
Trimming to the desired resistance value and tolerance is
accomplished by cutting the trim points, thereby producing
specific incremental changes in the chip’s resistance value
relative to the original prevalue; up to + 20 % for the V5X5P,
+ 30 % for the V15X5P, and + 50 % for the V15X10P (not all
trim points need be used; the ΔR necessary to adjust the
pre-value to the desired final value dictates which trim points
neet to be used).
Monitoring of circuit output while “actively” trimming readily
permits adjustment of the chip to ± 0.005 %.
Actual trimming charts are supplied on request for all images.

Vishay precision chip resistors offer an order of magnitude of
improvement over other chip resistors in hybrid applications.
With a maximum Temperature Coefficient of Resistance
(TCR) of ± 5 ppm/°C, selected TCR tracking to 0.5 ppm/°C
and factory supplied resistance tolerances to ± 0.01 %, they
provide the user with accuracy and stability not available in
other chip resistor products. If desired they can be user
trimmed to any value within ± 0.005 %.
Vishay precision chip resistors are designed to meet or
exceed the requirements of MIL-PRF-55342 characteristic E.
These discrete chips are available either factory trimmed to
exact resistance values (option T) or ready for user trimming
(option U).
