INTRODUCTION
Model VCS2516 are surface mount resistors designed with
4 pads for kelvin connection. 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 to make recommendations for non standard
technical requirements and special applications, Please
contact us.
