1) OCL (Open Circuit Inductance) Test parameters: 100kHz, 0.1Vrms, 0.0Adc
2) DC current for an approximate T 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 155°C under
worst case operating conditions verified in the end application.
3) Isat Amperes Peak for approximately 10% rolloff @ 20°C
4) Isat Amperes Peak for approximately 15% rolloff @ 20°C
5) K-factor: Used to determine B p-p for core loss (see graph). B p-p =K*L*I
B p-p:(Gauss), K: (K factor from table), L: (Inductance in uH), I (Peak to peak
ripple current in Amps).
