Notes
a.
Surface Mounted on 1” x 1” FR4 Board.
b.
See Solder Profile (http://www.vishay.com/doc?73257). The PowerPAK 1212-8 is a leadless package. The end of the lead terminal is exposed copper (not
plated) as a result of the singulation process in manufacturing. A solder fillet at the exposed copper tip cannot be guaranteed and is not required to ensure
adequate bottom side solder interconnection.
c.
Rework Conditions: manual soldering with a soldering iron is not recommended for leadless components.
