1 Open Circuit Inductance Test Parameters: 100 kHz, 0.1 V

rms, 0.0 Adc.

2 Irms: DC current for an approximate ΔT of 40 °C without core loss. Derating is necessary for AC

currents. PCB layout, trace thickness and width, air-flow, and proximity of other heat generating

components will affect the temperature rise. It is recommended that the temperature of the part not

exceed

+125 °C under worst case operating conditions verified in the end application.

3 Isat Amps peak for approximately 35% rolloff (@ +25 °C)

4 K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K*L*ΔI, Bp-p(mT), K: (K factor from

table), L: (Inductance in

μH), ΔI (Peak-to-peak ripple current in Amps).
