POPULAR OPTIONS
For any option it is recommended to consult Vishay Sfernice for availability first.
Option: Enlarged terminations:
For stringent and special power dissipation requirements, the thermal resistance between the resistive layer and the solder joint
can be reduced using enlarged terminations chip resistors which are soldered on large and thick copper pads acting as heatsink
(see application note: 53048 Power Dissipation in High Precision Vishay Sfernice Chip Resistors and Arrays (P Thin Film, PRA
Arrays, CHP Thick Film)
