Notes
a. Surface Mounted on 1” x 1” FR4 Board.
b. See Reliability Manual for profile. The ChipFET 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 intercon-
nection.
c. Rework Conditions: manual soldering with a soldering iron is not recommended for leadless components.
