NOTES:
1. The I_rated is either 85% of the I_saturation or the I_heating depending which is lower.
2. The I_saturation is the current which causes the inductance to drop by 15% of its nominal value.
3. The I_heating is the current which causes the temperature of the part to increase by approximately 45°C.
