"Tuning of the evaluated product is easy, the change of resistance is smooth, and it's very easy to set the voltage with accuracy of <0.1 %. Unlike normal trimmers, the slight force applied on the screw when trimming it doesn't have a detectable impact on the resistance value. By using this trimmer, the attenuation value can be set with an accuracy of <0.05 dB. As seen from the figures, the temperature stability is excellent."

"Vishay Foil Resistors' hermetically sealed VHA518-11 resistors have been subjected to a 5 year test to verify their long-term drift. The actual TCRs of less than 0.5 ppm/°C and long-term drifts of better than 2 ppm/year make the VHA518-11 suitable and very cost-effective secondary resistance standards in quantum Hall resistance measurements."

"In summary, the stability and reliability offered by VPG resistors maintains the high performance of ISL28617 throughout all environmental conditions. The ultra-low TCR of Bulk Metal® Z-Foil resistors reduces gain error due to thermal gradients and the low PCR provides the best linearity. This is ideal for applications where accurate and stable measurements are necessary regardless of external conditions exerted on the measurement systems."

"I was fortunate to have a senior sales director and applications engineer visit me in my laboratory and discuss my instrument set-up and difficulties using other resistor technologies. After our meeting and a demonstration, there was no doubt that my experiments could benefit from VFR technology. The field engineer promptly followed up with my future requests and helped get my experiments completed. I think it is obvious how precision measurements of this type can benefit from Vishay Foil Resistors technology."

"I have always relied upon Bulk Metal® Foil resistors for my most challenging projects, so in this case I didn’t waste any time looking at other options. The VPG foil resistors have top-class specs (best in the class), best sound (that cannot and have not been matched by any other resistor to-date), small size, almost any value availability, and are cost-effective – all of which makes them the No. 1 choice in the most demanding and critical circuits for high-end audio and analog design. No other resistor exists that can match all of the requirements for the sonics we aim to achieve."
