Figure 3. PCB Pad Print for Minipak 1412.

Package (mm [inches ]).

This pad print provides allow-

ance for package placement by

automated assembly equipment

without adding excessive

parasitics that could impair the

high frequency performance of

the ATF-541M4. The layout is

shown with a footprint of the

ATF-541M4 superimposed on the

PCB pads for reference.
