1 Open Circuit Inductance Test Parameters: 100 kHz, 0.1 Vrms, 0.0 Adc.
2Irms: 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.
3Isat 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 equals number of zeros.
-R suffix = RoHS compliant
