Document 757-1 Coupled Inductors LPD5030 For Flyback, SEPIC, Zeta and other Applications The LPD5030 coupled miniature shielded inductors are only 3 mm high and 5 mm square. They are ideal for use in a variety of circuits including flyback, multi-output buck and SEPIC. These inductors provide high inductance, high efficiency and excellent current handling in a rugged, low cost part. They can also be used as two single inductors connected in series or parallel or as a common mode choke. + + D L1 C L2 VOUT C VIN - SW - Typical Flyback Converter D L2 Dot indicates pin 1 1 + 4 D SW VOUT C - - Typical Buck Converter with auxiliary output L1 0.134 0.090 3,40 2,30 Recommended Land Pattern VIN 0.138 3,50 0.090 2,30 - 0.030 0,75 0.197 5,00 1 4 L2 3 0.060 1,50 0.134 3,40 0.197 5,00 Dimensions are in C + C1 L2 Q C + L2 C1 Q VIN VOUT - Typical SEPIC schematic + - 0.060 1,52 D + Internal code 45 typ 2 L1 3 0.114 0.004 2,90 0,10 L1 + VIN 0.189 0.003 4,80 0,076 XXX X Dash number AUX - 0.189 0.003 4,80 0,076 2 + VOUT C L1 C D Typical Zeta schematic C VOUT - inches mm US +1-847-639-6400 sales@coilcraft.com UK +44-1236-730595 sales@coilcraft-europe.com Taiwan +886-2-2264 3646 sales@coilcraft.com.tw China +86-21-6218 8074 sales@coilcraft.com.cn Singapore + 65-6484 8412 sales@coilcraft.com.sg Document 757-1 Revised 06/21/13 (c) Coilcraft Inc. 2013 This product may not be used in medical or high risk applications without prior Coilcraft approval.

Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). Packaging: C = 7 machine-ready reel. EIA-481 embossed plastic tape (750 parts per full reel). B = Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead. D = 13 machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (2500 parts per full reel). 2. Inductance shown for each winding, measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent. When leads are connected in parallel, inductance is the same value. When leads are connected in series, inductance is four times the value. 3. DCR is for each winding. When leads are connected in parallel, DCR is half the value. When leads are connected in series, DCR is twice the value. 4. SRF measured using an Agilent/HP 4191A or equivalent. When leads are connected in parallel, SRF is the same value. 5. Leakage Inductance is for L1 and is measured with L2 shorted. 6. DC current, at which the inductance drops the specified amount from its value without current. It is the sum of the current flowing in both windings. 7. Equal current when applied to each winding simultaneously that causes a 40C temperature rise from 25C ambient. See temperature rise calculation. 8. Maximum current when applied to one winding that causes a 40C temperature rise from 25C ambient. See temperature rise calculation. 9. Electrical specifications at 25C.
