The reference inductance at rated DC current is a typical value. 8. Limit the DC bias (H) to 46 orsteds. Calculate H by multiplying H1from the table 2. Temperature rise is 50°C in typical buck or boost circuits at 250kHz and by IDCof 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 10-18x B2.7x 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 ET100from the table, and multiply by 100. the stated operating temperature range.
