VCS1625 Vishay Foil Resistors High Precision Bulk Metal® Foil Surface Mount Current Sensing Chip Resistor with TCR of ± 2 ppm/°C and Load Life Stability of ± 0.02 % FEATURES INTRODUCTION Model VCS1625 is a surface mount resistor designed with 4 pads for Kelvin connection. Utilizing Vishay Bulk Metal® foil as the resistance element, it provides performance capabilities far greater than other resistor technologies can supply in a product of comparable size. 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. Gold terminations are available on special order. Our application engineering department is available to advise and to make recommendations. For non standard technical requirements and special applications, please contact us. • Temperature coefficient of resistance (TCR): ± 2.0 ppm/°C typical (- 55 °C to + 125 °C, + 25 °C ref.)
