RECOMMENDED PAD PATTERNS

1. Tolerance of inductance : 20%.

2. Irated is the DC current which cause the inductance drop less than 25% of its nominal inductance without current

and the surface temperature of the part increase less than 45 C.

3. Operating temperature: -20 Cto 105 C(including self-temperature rise).
