Notes:
1. R28 and R30 indicate the classification level. Full power midspan configuration is (R28 NP) (R30 = 2 k.
2. Although V1.3a EVBs are shipped with a non-shielded inductor, shielded inductor L1 is strongly recommended for EMI
performance considerations (See www.coilcraft.com/pdfs/mss1278t.pdf).
3. The capacitor is radial-leaded and can be used if the height restriction is not an issue.
