VCS1625Z Ultra High Precision Z-Foil

Ultra high precision Z-Foil surface mount current sensing chip resistor with TCR of ± 0.05 ppm/°C and power coefficient of 5 ppm at rated power

Image of Vishay Foil Resistors' VCS1625Z Ultra High Precision Z-Foil  Surface Mount Current Sensing Chip ResistorVishay Precision Group's VCS1625Z series is a surface mount chip resistor designed with 4 pads for Kelvin connection. Utilizing Vishay Precision Group'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.

The Z-Foil technology provides a significant reduction of the resistive component's sensitivity to ambient temperature variations (TCR) and applied power changes (PCR). Designers can now guarantee a high degree of stability and accuracy in fixed-resistor applications using solutions based on Vishay Precision Group's revolutionary Z-Foil technology.
