The 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.
Temperature coefficient of resistance (TCR): ± 0.05 ppm/°C typical (0 °C to + 60 °C) ± 0.2 ppm/°C typical (- 55 °C to + 125 °C, + 25 °C ref.)
Resistance range: 0.3 Ω to 10 Ω
Tolerance: to ± 0.2 %
Power coefficient “DeltaR due to self heating”: 5 ppm at rated power
Load life stability: 0.02 % at 70 °C, 2000 h at rated power
