Core loss approximation is based on published core data: 1.12 2.17 3. The rated current listed is the lower of the saturation current Core Loss = K1 * (f) * (K2I) 25C, 100C, or the heating current. Where: Core Loss = in Watts 4. The saturation current, ISAT, is the current at which the K1= 8.74E-11 f = switching frequency in kHz component inductance drops by 20% (typical) at an ambient K1 & K2 = core loss factors temperature of 25C and 100C. This current is determined by I = delta I across the component in Ampere placing the component in the specified ambient environment K2I = one half of the peak to peak flux density and applying a short duration pulse current (to eliminate across the component in Gauss self-heating effects) to the component. 7. Unless otherwise specified, all testing is made at 5. The heating current, IDC, is the DC current required to raise the 100kHz, 0.1VAC. component temperature by approximately 40C. The heating 8. Optional Tape & Reel packaging can be ordered by adding a current is determined by mounting the component on a typical suffix to the part number (i.e. PG0437.401NL becomes PCB and applying current for 30 minutes.
