Vishay Precision Group Inc. announced that its Vishay Foil Resistors brand (VFR) has introduced a new series of military-qualified, ultra-high-precision Z1-Foil wrap-around chip resistors. Tested per EEE-INST-002 (Tables 2A and 3A, Film/Foil, Level 1) and MIL-PRF-55342, devices in the 303261 - 303266 seriesprovide exceptional load-life stability of ±0.0025% typical after rated power at 70°C for 2,000 hours, low nominal TCR of ±0.2 ppm/°C from -55°C to +125°C, +25°C ref., PCR (ΔR due to self heating) of 5 ppm at rated power, and tight tolerances to ±0.02%.

Vishay Precision Group Inc. announced that its Vishay Foil Resistors brand (VFR) has enhanced its VFCP series of Bulk Metal® Z-Foil ultra-high-precision flip chip resistors with an extended resistance range down to 5 Ω. The devices feature ultra-low TCR of ±0.05 ppm/°C nominal (0°C to +60°C) and ±0.2 ppm/°C typical (-55°C to +125°C, +25°C ref.) and load-life stability of ±0.005% at 70°C for 2,000 hours at rated power and ±0.01% at 70°C for 10,000 hours. 

Vishay Precision Group Inc. announced that the company has opened a new Vishay Foil Resistors (VFR) Precision Center within Digi-Key Corp., a global full-service provider of both prototype/design and production-quality electronic components. Digi-Key can now build and ship VFR surface-mount precision resistors — with no minimum quantities — in 24 to 48 hours, including VFR's popular new Bulk Metal® Foil VSMP (Z-Foil Technology) and VSM series resistors.

Vishay Precision Group Inc. announced that its Vishay Foil Resistors (VFR) brand has released a new video that compares the stability and accuracy of three different current sense precision resistor technologies used in solar panels: thick film, metal band, and next-generation Bulk Metal® Z-Foil. The short video demonstrates how an increase in ambient temperature results in a change in accuracy and stability in thick film and metal band resistors; but has no effect on the Z-Foil resistor.

Vishay Precision Group Inc. unveiled a new demonstration video that shows the actual process by which the company's Vishay Foil Resistors (VFR) brand is able to ship samples of Bulk Metal® Foil precision resistors within any resistance value within a 0.01% tolerance within one to five days.
