(1) Open Circuit Inductance Test Parameters: 100kHz, 0.1V, 0.0Adc.
(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 125°C under worst
case 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).
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).
(5) Part Number definition: DR1030-xxx-R
DR1030 = Product code and size, xxx = Inductance value in µH, R = decimal
point. If no R is present third character = # of zeros. -R suffix = RoHS compliant
