1. Open Circuit Inductance Test Parameters: 100kHz, 0.1V, 0.0Adc.
2. I
rms
: 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. I
sat
Amps peak for approximately 35% rolloff (@25°C)
4. K-factor: Used to determine B

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 = # of zeros.
-R suffix = RoHS compliant
