Limit the DC bias (H) to 46 orsteds. Calculate H by multiplying H1 from the table 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 by IDC of the application. with the reference ET applied to the inductor. 9. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the part 3. Total loss in the inductor is 380mW for 50°C temperature rise above ambient. number (i.e. P0144NL becomes P0144NLT). Pulse complies to industry standard 4. To estimate temperature rise in a given application, determine copper and tape and reel specification EIA481. core losses, divide by 380 and multiply by 50. 10. The "NL" suffix indicates an RoHS-compliant part number. Non-NL suffixed parts 5. For the copper loss (mW), calculate IDC2 X RN. are not necessarily RoHS compliant, but are electrically and mechanically equivalent 6. For core loss (mW), using frequency (f in Hertz) and operating flux density to NL versions. If a part number does not have the "NL" suffix, but an RoHS (B in Gauss), calculate 6.11 x 10-18 x B2.7 x f2.04. compliant version is required, please contact Pulse for availability. 7. For flux density (B in Gauss), calculate ET (V-µsec) for the application, divide 11. The temperature of the component (ambient plus temperature rise) must be within by ET100 from the table, and multiply by 100. the stated operating temperature range.
