Low-Profile Shielded Drum Inductors
SD7030 Series
07-08 SB08287 Page 1 of 3 Data Sheet: 4330
SMD Device
(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
p-p
for core loss (see graph). B
p-p
= K*L*ΔI,B
p-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
