1. Open Circuit Inductance (OCL) Test Parameters: 100 kHz, 0.1 Vrms, 0.0 Adc, +25 °C
2. Full Load Inductance (FLL) Test Parameters: 100 kHz, 0.1 Vrms, Isat1, +25 °C
3. I
rms
: DC current for an approximate temperature rise 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.
4. I

1
: Peak current for approximately 20% rolloff @ +25 °C
5. I

. Bp-p:(Gauss),
K: (K-factor from table), L: (Inductance in nH), Symbol I (Peak to peak ripple current in Amps).
