Notes:

1) I sat: The current when the inductance becomes 10% lower than its initial value (Ta = 20°C).

2) I rms: The current when temperature of coil increase up to max. ΔT ≤ 40°C (Ta = 20°C).

• Test equipment

L: measured on Agilent 4284A LCR meter or equivalent

DCR: measured on Chroma 16502 micro-OHM meter or equivalent

I sat & I rms: measured on Agilent 4284A LCR meter with 42841A Current Source or equivalent.
