1. 1. Open Circuit Inductance (OCL) 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 125 °C under worst case operating conditions

verified in the end application

3. lsat: Peak current for approximately 30% rolloff @ 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: SD53-xxx-R

SD53 = Product code and size; -xxx = Inductance value in uH; R = decimal point;

If no R is present then third character equals the number of zeros.

-R suffix = RoHS compliant.
