Copper paths must not be routed beneath the power
module mounting inserts. Recommended SMT layout
shown in the mechanical section are for reference
only. SMT layout depends on the end PCB
configuration and the location of the load. For
additional layout guide-lines, refer to FLTR100V10
data sheet or contact your local Lineage Power field
application engineer.
