RECOMMENDED PAD PATTERNS  
1. Tolerance of inductance is  20%.
2. Isat is the DC current which cause the inductance drop approximately 20% of is nominal inductance without current.
O
3. Irms is the DC current which cause the surface temperature of the part increase less than 45 C. 
OO
4. Operating temperature :  -20 C to 105 C ( including self-temperature rise ).
