1. Open Circuit Inductance Test Parameters: 100 kHz, 0.1 Vrms, 0.0 Adc.

2. Irms: DC current for an approximate ΔT 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 Amps peak for approximately 35% rolloff (@ +25 °C)

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

Bp-p = K*L*ΔI, Bp-p (mT), K: (K factor from table), L: (Inductance in µH), ΔI (Peak to

peak ripple current in Amps).

5. Part Number Definition: SD8350-xxx-R

SD8350 = Product code and size; -xxx = Inductance value in µH;

R = decimal point; If no R is present, third character

equals number of zeros.

-R suffix = RoHS compliant
