6. For core loss, using frequency (f) and operating flux density (B),

calculate 6.11 x 10^-18x B^2.7x f^2.04

7. For flux density (B), calculate ET (V-µsec) for the application, divide by

ET¹⁰⁰from the table, and multiply by 100.

8. Limit the DC bias (H) to 46 orsteds. Calculate H by multiplying H¹from

the table by I^DCof the application.

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 250 KHz and with the

reference ET applied to the inductor.

3. Total loss in the inductor is 380 mWatts 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^DC²X RN.
