| VCS2516 Vishay Foil Resistors SURFACE MOUNT Bulk Metal(R) Foil Technology Surface Mount Current Sensing Chip Resistors FEATURES * Low Ohmic Values: 0.01 to 1.0 * Resistance Tolerance: to 1.0% * Low Temperature Coefficient of Resistance * Power Rating: 1 watt at + 85C Product may not be to scale * Current Rating: 5 Amperes maximum * Tin/Lead Coated Terminations Standard * Gold Plated Terminations Available on Special Order (Special Part Number Required) Model VCS chip resistors have 4 tin/lead coated surface mount pads for 4-terminal connection where a current sensor is required. Utilizing Vishay Bulk Metal(R) Foil as the resistance element, they provide performance capabilities far greater than other resistor technologies can supply in a product of comparable size. These small devices dissipate the heat almost entirely through the pads so surface mount users are encouraged to be generous with the pads and board traces. Some hybrid users may want to use conductive epoxy for the interconnection and gold terminations are available on special order. (Tin/lead oxidizes on the surface and the conductive epoxy joint eventually fails electrically.) TABLE 1 - TEMPERATURE COEFFICIENT OF RESISTANCE - 55C TO + 125C, + 25C REF.
