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 250kHz and
with the reference ET applied to the inductor.
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, calculate IDC² X RN.
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.
Mechanical
7. For flux density (B), calculate ET (V-µsec) for the application, divide by ET100
from the table, and multiply by 100.
8. Limit the DC bias (H) to 46 orsteds. Calculate H by multiplying H1 from the table
by IDC of the application.
9. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the part
number (i.e. PL8500 becomes PL8500T). Pulse complies to industry standard
tape and reel specification EIA481.
