Note 1 - DC Current (Irms) is current which causes a maximum temperature rise of 40°C:

Condition A = 4-layer PWB (1.6t, FR4)

Condition B = PWB with high dissipation performance, heat radiation constant is approximately 27K/W measured for

8.5mm x 8.0mm x 5.4mm case size.

Note 2 - DC Current (Isat) is current which causes a decrease in inductance of 30%.

Note 3 - Highest operating temperature should be within +150°C including temperature rise due to self-heating.
