NOTES:
1. The reference inductance at rated DC current is a typical value.
2. Temperature rise is 50°C in typical buck or boost circuits at 250 KHz and with the
reference ET applied to the inductor.
6. For core loss, using frequency (f) and operating flux density (B),
calculate 6.11 x 10-18 x B2.7 x f2.04
7. For flux density (B), calculate ET (V-µsec) for the application, divide by ET100 from
the table, and multiply by 100.
.
3. Total loss in the inductor is 380 mWatts for a 50°C temperature rise above ambient.
4. To estimate temperature rise in a given application, determine copper and core
losses, divide by 380 and multiply by 50.
8. Limit the DC bias (H) to 46 orsteds. Calculate H by multiplying H1 from the table by
IDC of the application.
9. The maximum DCR listed is approximately 17ꢀ over the nominal DCR.
10. Add suffix "T" to part number for tape and reel package (i.e. P0183T).
5. For the copper loss, calculate IDC 2X RN.
