Inductance at Irated is a typical inductance value for the component taken at rated current. 2. The rated current listed is the lower of the saturation current @ 25°C or the heating current. 4. The heating current, IDC, is the DC current required to raise the component temperature by approximately 45°C. The heating current is determined by mounting the component on a typical PCB and applying current for 30 minutes. 3. The saturation current, Isat, is the current at which the component inductance drops by 10% (maximum) at an ambient temperature of 25°C. This current is determined by placing the component in the specified ambient environment and applying a short duration pulse current (to eliminate self-heating effects) to the component. 5. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the part number (i.e. PF0580.102NL becomes PF0580.102NLT). Pulse complies to industry standard tape and reel specification EIA481. 6. The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range.
