INTRODUCTION
Model VCS2516 chip resistors have 4 tin/lead coated
surface mount pads for 4-terminal connection where a
current sensor is required. Utilizing Vishay Bulk Metal
®
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.)
Lead (Pb)-free terminations (100% Sn) are also availiable.
Our Application Engineering Department is prepared to
advise and recommend for non standard technical
requirements and special applications, Please contact us.
