(1) Open Circuit Inductance Test Parameters:100kHz, 0.1V, 0.0Adc.

(2) Irms:DC current for an approximate ∆Tof 40°C without core loss.Derating isnecessary for AC currents.PCB layout, trace thickness and width, air-flow, andproximity of other heat generating components will affect the temperature rise.Itis recommended that the temperature of the part not exceed 125°C under worstcase operating conditions verified in the end application.

(3) Isat Amperes peak for approximately 35% rolloff max.(@25°C)(4) K-factor:Used to determine B p-p for core loss (see graph).

Bp-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).(5) Part Number definition:DR1030-xxx-R
