NOTES:
1. The reference inductance at rated DC current is a typical value.
2. Temperature rise is 50擄C in typical buck or boost circuits at 250 KHz and with the
reference ET applied to the inductor.
3. Total loss in the inductor is 380 mWatts for a 50擄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.
5. For the copper loss, calculate I
DC
2
X R
N
.
6. For core loss, using frequency (f) and operating flux density (B),
calculate 6.11 x 10
-18
x B
2.7
x f
2.04
.
7. For flux density (B), calculate ET (V-碌sec) for the application, divide by ET
100
from
the table, and multiply by 100.
8. Limit the DC bias (H) to 46 orsteds. Calculate H by multiplying H
1
from the table by
I
DC
of the application.
9. The maximum DCR listed is approximately 17% over the nominal DCR.
10. Add suffix
"T"
to part number for tape and reel package (i.e. P0183T).
