RECOMMENDED PAD PATTERNS  
1. Tolerance of inductance : 0.36uH  30%   0.80~8.80uH  20%
2. IRATED is the DC current which cause the inductance drop less than 35% 
   (20% typical) of its nominal inductance without current and the surface 
O
   temperature of the part increase less than 45 C. 
OO
3. Operating temperature :  -20 C to 105 C ( including self-temperature rise ).  
RoHS  compliant.
