The reference inductance is a typical value at the AC and DC excitation listed. 2. Temperature rise is 55°C in typical buck or boost circuits at 100 KHz and with the reference ET applied to the inductor. 3. Total loss in the inductor is 634 mWatts for a 55°C temperature rise above ambient. 4. To estimate temperature rise in a given application, determine copper and core losses, divide by 634 and multiply by 50. 5. For the copper loss, calculate IDC 2X RN. 6. For core loss (mW), using frequency (f in Hertz) and operating flux density (B in Gauss), calculate 2.24 x 10-10 x B2.11 x f1.26. 7. For flux density (B), calculate ET (V-µsec) for the application, divide by ET100 from the table, and multiply by 100. 8. For estimating L with DC current, calculate H by multiplying H1 from the table by IDC of the application. Using H, determine the DC perm Factor (FUDC). Multiply LW/O DC by FUDC for L @ DC. 9. Add suffix "T" to part number for tape and reel package (i.e. P0395T).
