The compute keeps scaling.Our precision keeps it stable.

where precision meets the compute buildout.

every generation of AI compute pushes more power through smaller boards at tighter tolerances. VPG supplies the precision resistors and sensing that let chipmakers, data center operators, and instrumentation OEMs hold accuracy as density and power climb.

current-sense and power resistors hold their value under the thermal load of rack-scale AI compute, so power delivery stays in spec as GPU power draw climbs.

pin electronics and probe cards built on ultra-stable foil resistors keep GPU and HBM wafer test accurate through millions of touchdowns.

from calibration labs to cryogenic qubit control, ultra-precision foil resistors give metrology and quantum hardware a reference that doesn't drift.
