Utilizing Vishay Bulk Metal ® Foil as the resistance elemen t, it provides performance capabilities far greater than other resistor technologies can supply in a product of comparable size. Low TCR removes errors due to temperature gradients. The VCS1610 has improved load life stability of ± 0.02 % at + 70 °C for 2000 h at rated power. Other technologies of current sensing resistors offer a load life stability of ≥ 0.5 % through a 1000 h workload. 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.
