1 Open Circuit Inductance Test Parameters: 100kHz, 0.1V, 0.0Adc.
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: SD7030-xxx-R
SD7030 = 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
