(1) Open Circuit Inductance Test Parameters: 100kHz, 0.25V, 0.0Adc.

(4) K-factor: Used to determine B p-p for core loss (see graph).

(2) Irms: DC current for an approximate ³T 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*³I, B p-p(mT), K: (K factor from table), L: (Inductance in µH),

³I (Peak to peak ripple current in Amps).

(5) Part Number Definition: DR124-xxx-R

DR124 = 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 25% rolloff (@25°C)
