The saturation current is the typical current which causes the inductance to drop by 20% at the stated ambient Pulse complies to industry standard tape and reel specification EIA481. The tape and reel for this product has a temperatures (25C, 100C and 125C).

The heating current is the DC current which causes the part temperature to increase by approximately 40C when used in a typical application.
