FB = Dale ILB1206 - 300 (300â¦ @ 100 MHz) or TDK ACB2012L-120

Ceramic Caps C1 & C3, C5 = 10 â 22 ÂµF C2 & C4 = 0.005 ÂµF C6 = 0.1 ÂµF

G = VIA to GND plane layer V =VIA to respective supply plane trace

Note: Each supply plane or strip should have a ferrite bead and capacitors

All VDD by pass capacitors = 0.1 ÂµF
