OCL: Open Circuit Inductance test parameters: 100 kHz, 0.1 Vrms, 0.0 Adc.
(2)
Irms: 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
+105
°C under
worst case operating conditions verified in the end application.
(3)
Isat Amperes peak for approximately 20% rolloff (@+20 °C)
(4)
Isat Amperes peak for approximately 30% 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),
∆(Peak
to peak ripple current in Amps).
