CROSS-SECTION
ELECTRICAL PERFORMANCE
Electrical parasitic data is highly dependent on the package layout. 3D electrical simulation can be used on the specific package design
to provide the best prediction of electrical behavior. Data below is for a frequency of 100MHz and assumes 1.0 mil gold bonding wire.
