The temperature of the component (ambient plus temperature rise) muse be within thestandard operating temperature range. 2. Inductance at Irated is a typical inductance value for the component taken at rated current. 3. The rated current listed is the lower of the saturation current @ 25°C or the heating current. 4. The saturation current, ISAT, is the current at which the component inductance drops by 20%(typical) 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. The heating current, IDC, is the DC current required to raise the component tempera- ture by approximately 40°C. The heating current is determined by mounting the component on a typical PCB and applying current for 30 minutes. The temperature is measured by placing the thermocouple on top of the unit under test. Take note that the component’s performance varies depending on the system condition. It is sug- gested that the component be tested at the system level, to verify the temperature rise of the component during system operation. 6. Core Loss approximation is based on published core data: Core Loss = K1*(f)1.035 *(K2ΔI)2.263 Where: Core Loss = in Watts f = switching frequency in kHz K1 & K2 = core loss factors ΔI = delta I across the component in Ampere K2ΔI = one half of the peak to peak flux density across the component in Gauss 7. Unless otherwise specified, all testing is made at 100kHz, 0.1VAC. 8. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part standard tape and reel specification EIA481. * Contact Pulse for availability Notes:
