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 100kHz and with the
reference ET applied to the inductor.
3. Total loss in the inductor is 634mW 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 (mW), calculate I
DC

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 in Gauss), calculate ET (V-µsec) for the application, divide by
ET
100
from the table, and multiply by 100.
8. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to
the part number (i.e. P0395NL becomes P0395NLT). Pulse complies to indus-
try standard tape and reel specification EIA481.
9. 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.
10. The temperature of the component (ambient plus temperature rise) must be within
the stated operating temperature range.
