(2) Irms: DC current for an approximate DT 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 Amperes peak for approximately 30% rolloff (@+20 °C) (4) K-factor: Used to determine B p-p for core loss (see graph). B p-p = K*L*∆I, B p-p(mT), K: (K factor from table), L: (Inductance in uH), ∆(Peak to peak ripple current in Amps). Dimensions- mm Dimensions are in millimeters. Part Marking: 3 Digit Marking: (1st digit: Indicates inductance value per letter in Part Marking Designator); (2nd digit: Bi-weekly production date code); (3rd digit: Last digit of the year produced). Do not route traces or vias underneath the inductor Packaging information- mm Parts packaged on 13" Diameter reel, 4,100 parts per reel. 2 www.eaton.com/electronics SD3110 Low profile metalized shielded drum core power inductors Technical Data 4137 Effective October 2017 Temperature rise vs total loss loss TemperautreRise (°C) 90 80 70 60 50 40 30 20 10 0 l i t n u r 14 o 6 31 nt. 1 0 SD me 2 , 1 3 view lace p y l e e r u e r J e e eas at v i t Pl ern c t fe d. l f a E te n , a e d l e ep as u ) n sd i 8 t 2 n yi 1 o sc tor t (4 i D en ee inv ta sh da 0 0.05 0.1 0.15 0.2 0.25 0.3 0.35 0.4 0.45 Total Loss (W) Core loss vs Bp-p 10 1MHz 1 500kHz 300kHz 200kHz 0.1 100kHz Core Loss (W) 0.01 50kHz 0.001 0.0001 0.00001 0.000001 1 10 100 1000 Bp-p (mT) Inductance characteristics 12 120% 0% 11 110% 0% 10 100% 0% 90% 90 % %% ooff OOCCLL 80% 80 % 70% 70 % -40°C 60% 60 % 50% 50 % 25°C 40% 40 % 30% 30 % 85°C 20% 20 % 10% 10 % 0% 0% 1 0% 20 % 30% 40% 50 % 6 0% 70% 80% 90 % 100% 1 10 % 120% 130% 140% %% of o f I Is s a a tt www.eaton.com/electronics 3 SD3112 Low profile metalized shielded drum core power inductors Technical Data 4127 Effective October 2017 Solder Reflow Profile TP tP Max.
