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 I DC2 X RN. 6. For core loss, using frequency (f) and operating flux density (B), calculate 6.11 x 10-18 x B2.7 x f2.04. 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 PL8500 T). Pulse complies to industry standard tape and reel specification EIA481. NOTES: www.pulseeng.com M113.A (10/05) For More Information: Pulse Worldwide Headquarters
