NOTES:
1. Temperature rise is 50°C in typical buck or boost circuits at 250kHz and with the
reference ET applied to the inductor.
2. Total loss in the inductor is 380mW for a 50°C temperature rise above ambient.
3. To estimate temperature rise in a given application, determine copper and core
losses, divide by 380 and multiply by 50.
4. For the copper loss (mW), calculate IDC2 X RN.
5. 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.
6. For flux density (B in Gauss), calculate ET (V-µsec) for the application, divide by
ET100 from the table, and multiply by 100.
7. Limit the DC bias (H) to 46 orsteds. Calculate H by multiplying H1 from the table
by IDC of the application.
8. The maximum DCR listed is approximately 17% over the nominal DCR.
9. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to
the part number (i.e. P0174NL becomes P0174NLT). 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.
