Electrical Specifications @ 25°C — Operating Temperature -40°C to +130°C
NOTES:
1. 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 I
DC
2
X R
N
.
6. For core loss (mW), using frequency (f in Hertz) and operating flux density (B in
Gauss), calculate 2.24 x 10
-10
x B
2.11
x f
1.26
.
7. For flux density (B), calculate ET (V-μsec) for the application, divide by ET
100
from
the table, and multiply by 100.
8. For estimating L with DC current, calculate H by multiplying H
from the table by
I
DC
of the application. Using H, determine the DC perm Factor (F
UDC
). Multiply
L
DC by F
UDC
for L @ DC.
