(1) Open Circuit Inductance Test Parameters: 100kHz, 0.1V, 0.0Adc.
(4) K-factor: Used to determine B p-p for core loss (see graph).
(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.
B p-p = K*L*∆I, B p-p(mT), K: (K factor from table), L: (Inductance in µH),
∆I (Peak to peak ripple current in Amps).
(5) Part Number Definition: DR1050-xxx-R
DR1050 = Product code and size; -xxx = Inductance value in uH;
R = decimal point; If no R is present, third character = # of zeros.
-R suffix = RoHS compliant
(3) Isat Amperes peak for approximately 35% rolloff (@25°C)
