PCB pad layout , trace thickness and width , air-flow and proximity of other heat generating components will affect the
temperature rise. It is recommended the part temperature not exceed 130 ℃ under worst case operating conditions
verified in the end application.
5. The nominal DCR is measured from point "a" to point "b“ , as shown above on the mechanical drawing.

3 Irms: DC current for an approximate temperature rise of 40°C without core loss. Derating is
necessary for AC currents. PCB pad layout, trace thickness and width, air-flow and proximity of
other heat generating components will affect the temperature rise. It is recommended the part
temperature not exceed 125°C under worst case operating conditions verified in the end
application.
4 Isat1: Peak current for approximately 20% rolloff at +25°C.
5 Isat2: Peak current for approximately 20% rolloff at +125°C.
6 K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * ΔI * 10-3, Bp-p : (Gauss),
K: (K-factor from table), L: (inductance in nH), ΔI (peak-to-peak ripple current in amps).
