RECOMMENDED PAD PATTERNS
1. Tolerance of inductance: 30% for 1.7~6.8uH; 20% for 10~33uH.
2. Isat is the DC current which cause the inductance drop 35% typical of its nominal inductance without current.
3. Ir is the DC current which cause the surface temperature of the part increase less than
4.Operating temperature : -20
to 105
(including self-temperature rise).
