At PCB design time, we explicitly retain the freedom to populate a # capacitor, an inductor or a 0R jumper for the series component of each Pi # network, and as for each of the 4 ground legs in total, leave it unpopulated, # populate a capacitor, or populate an inductor. We are going to use RLC # reference designators for these generalized 0402 footprints.
