NOTES:
1. Temperature rise is 55°C in typical buck or boost circuits
operating at 300 KHz with the rated Idc current and reference
ET applied to the inductor.
2. Total loss in the inductor is 1.8 watts for 55°C temperature rise
above ambient.
3. To estimate temperature rise in a given application, determine
total losses (copper losses + core losses) and apply this formula:
TempRise (C) = (Total Losses(W))
.833
x 33.783
4. For copper losses, calculate: CopperLoss(mW) = Idc
2
x DCR
5. For core loss, using frequency (f: hertz) and flux density
(B: gauss): CoreLoss(mW) = 1.0769E-09 * f
1.26
x B
2.11
6. For flux density (B), calculate ET (V-
μ
sec) for the application, and
multiply by the ET
100
factor from the table.
7. Add suffix
"T"
to part number for tape and reel package (i.e.
P0595
T
).
