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 250kHz and
with the reference ET applied to the inductor.
NOTES:
8. Limit the DC bias (H) to 46 orsteds. Calculate H by multiplying H
by IDC of the application.
9. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the part
number (i.e. P0144NL becomes P0144NLT). Pulse complies to industry standard
tape and reel specification EIA481.
10. The "NL" suffix indicates an RoHS-compliant part number. Non-NL suffixed parts
are not necessarily RoHS compliant, but are electrically and mechanically equivalent
to NL versions. If a part number does not have the "NL" suffix, but an RoHS
compliant version is required, please contact Pulse for availability.
11. The temperature of the component (ambient plus temperature rise) must be within
the stated operating temperature range.

from the table
3. Total loss in the inductor is 380mW for 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.
5. For the copper loss (mW), calculate IDC2 X R
N.
6. For core loss (mW), using frequency (f in Hertz) and operating flux density
(B in Gauss), calculate 6.11 x 10-18 x B2.7 x f2.04
.
7. For flux density (B in Gauss), calculate ET (V-µsec) for the application, divide
by ET100 from the table, and multiply by 100.
