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).
