(1) Open Circuit Inductance Test Parameters: 100kHz, 0.1V, 0.0Adc.
(2) Irms: DC current for an approximate DT 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 Amperes peak for approximately 30% rolloff (@20°C)
(4) K-factor: Used to determine B p-p for core loss (see graph).
B p-p = K*L*
I, B p-p(mT), K: (K factor from table), L: (Inductance in uH),
I (Peak to peak ripple current in Amps).
