Designers can now guarantee a high degree of stability and accuracy in fixed-resistor applications using solutions based on Vishay‘s revolutionary Z-foil technology. Model VCS1625Z is a surface mount chip resistor designed with 4 pads for Kelvin connection. Utilizing Vishay’s Bulk Metal® Z-foil as the resistance element, it provides performance capabilities far greater than other resistor technologies can supply in a product of comparable size. 0.05 ppm/°C absolute TCR removes errors due to temperature gradients. This small device dissipates heat almost entirely through the pads so surface mount users are encouraged to be generous with the board’s pads and traces.
