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 heat sinks (see application note:

“Power Dissipation in High Precision Vishay Sfernice Chip

Resistors and Arrays (P Thin Film, PRA Arrays, CHP Thick

Film)”: www.vishay.com/doc?53048).

For enlarged terminations: Please consult Vishay Sfernice.

PACKAGING

PACKAGING RULES

Several types of packaging are proposed: waffle-pack and

tape and reel

Waffle Pack

Can be filled up to maximum quantity indicated in the table

here above, taking into account the minimum order quantity.

When quantity ordered exceeds maximum quantity of a

single waffle pack, the waffle packs are stacked up on the top

of each other and closed by one single cover.

To get “not stacked up” waffle pack in case of ordered

quantity > maximum number of pieces per package:

Please concult Vishay/Sfernice for specific ordering
