The typical pattern and trimming illustrations show that the  
V5X5Z resistor has 16 trimming points, and the V15X5Z has  
20. 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 V5X5Z, + 30 % for the  
The Vishay precision trimming system allows for adjustment  
to precise resistance values without concern over  
mechanical override and control problems encountered in  
laser or air abrade trimming of solid geometry resistance  
patterns. This ability to trim resistor chips to tolerance levels  
never before available to hybrid manufacturers, now gives a  
project manager the ability to increase the value-added level  
of their hybrid services. More of the profit thus available can  
be retained within the facility. Now, instead of buying  
precision resistors in separate packages or modules (which  
require additional PC board real estate) and integrating them  
into a system, the project manager can utilize Vishay  
precision resistor chips or matched sets to manufacture the  
entire hybrid circuit in-house. Eliminates the need to “pin-out”  
for precision resistor requirements because the precision  
resistors are inside - part of the hybrid microcircuit design.  
V15X5Z (not all trim points need be used; the ΔR necessary  
to adjust the pre-value to the desired final value dictates  
which trim points need 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 ± 2 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 %, where  
the value remains stable after trimming. Load life stability is  
0.05 % ΔR maximum under full rated power for 2000 h at  
+ 70 °C.  
Vishay precision chip resistors are available either factory-  
trimmed to exact resistance values (option T) or ready for  
user trimming (option U); user trimming can be done either  
before or after bonding - using standard epoxies - onto the  
hybrid circuit substrate using standard laser, air abrade, or  
manual adjustment techniques. However care should be  
taken that no carbonization occurs when laser trimming.
