Document 757-1 For Flyback, SEPIC, Zeta Coupled Inductors LPD5030 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 C V L1 L2 OUT C V IN SW Typical Flyback Converter + D V OUT C AUX L2 0.189 0.003 4,80 0,076 Dot indicates pin 1 ++ L1 14 V V C OUT D IN SW 0.189 0.003 4,80 0,076 Typical Buck Converter with auxiliary output XXXX 23 D ++ Dash Internal number code L1 C1 V V C Q L2 C OUT IN Recommended LandPattern 0.114 0.004 2,90 0,10 0.138 3,50 Typical SEPIC schematic 0.090 2,30 45 ++ typ L2 C1 Q 0.134 0.090 0.197 0.030 V D V CCL1 OUT IN 3,40 2,30 5,00 0,75 Typical Zeta schematic 0.060 0.060 1,52 1,50 0.134 3,40 1 4 0.197 5,00 L1 L2 inches Dimensions are in mm 3 2 Document 757-1 Revised 06/21/13 US +1-847-639-6400 sales coilcraft.com UK +44-1236-730595 sales coilcraft-europe.com Coilcraft Inc. 2013 This product may not be used in medical or high Taiwan +886-2-2264 3646 sales coilcraft.com.tw risk applications without prior Coilcraft approval.

When leads Winding to winding isolation 100 V are connected in parallel, inductance is the same value. When leads Resistance to soldering heat Max three 40 second reflows at are connected in series, inductance is four times the value. +260C, parts cooled to room temperature between cycles 3. DCR is for each winding. When leads are connected in parallel, DCR Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30C / is half the value. When leads are connected in series, DCR is twice the 85% relative humidity) value. Mean Time Between Failures (MTBF) 26,315,789 hours 4. SRF measured using an Agilent/HP 4191A or equivalent. When leads Packaging 750/7 reel 2500/13 reel Plastic tape: 12 mm wide, are connected in parallel, SRF is the same value. 0.32 mm thick, 8 mm pocket spacing, 3.1 mm pocket depth 5. Leakage Inductance is for L1 and is measured with L2 shorted. Recommended pick and place nozzle OD: 5 mm ID: 2.5 mm 6. DC current, at which the inductance drops the specified amount from PCB washing Only pure water or alcohol recommended 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. Refer to Doc 639 Selecting Coupled Inductors for SEPIC Applications. Refer to Doc 362 Soldering Surface Mount Components before soldering.
