NOTE:  Minimum damping resistance is calculated from 0.35 
Ω – DCR

.  From vendor provided data, L1 and L2 
DCR
min
 is 0.4
Ω and 0.5Ω respectively, qualifying them for zero required trace resistance.  DCR

 for L3 is 
not known and is assumed to be 0.15
Ω. Products with equivalent specifications may also be used.
