Limit the DC bias (H) to 46 orsteds. Calculate H by multiplying H1 from the table 1. Temperature rise is 50°C in typical buck or boost circuits at 250kHz and with the by IDC of the application. reference ET applied to the inductor. 8. The maximum DCR listed is approximately 17% over the nominal DCR. 2. Total loss in the inductor is 380mW for a 50°C temperature rise above ambient. 9. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to 3. To estimate temperature rise in a given application, determine copper and core the part number (i.e. P0174NL becomes P0174NLT). Pulse complies to industry losses, divide by 380 and multiply by 50. standard tape and reel specification EIA481. 2 4. For the copper loss (mW), calculate IDC X RN. 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 5. For core loss (mW), using frequency (f in Hertz) and operating flux density (B in -18 2.7 2.04 NL versions. If a part number does not have the "NL" suffix, but an RoHS compliant Gauss), calculate 6.11 x 10 x B x f . version is required, please contact Pulse for availability. 6. For flux density (B in Gauss), calculate ET (V-µsec) for the application, divide by 11. The temperature of the component (ambient plus temperature rise) must be within ET100 from the table, and multiply by 100. the stated operating temperature range.
