Document 752-1 CoupledInductors–LPR6235 Document 752-1 Revised 09/24/13 • Can be used as step-up or flyback transformers in DC-DC converters or as autotransformers • Perfect for low voltage step-up in energy harvesting applications • Selected by Linear Technology for the LTC3108 and LTC3109 Ultralow Voltage Step-Up Converter and Power Managers Primary (L1) DCR max SRF Part Turns inductance2 (Ohms) typ3 Isat4 number1 ratio ±20% (µH) L1 L2 (kHz) (A) LPR6235-253LML_ 1 : 10 25 0.74 13.7 1300 1.3 LPR6235-253PML_ 1 : 20 25 0.20 72 580 0.7 LPR6235-123QML_ 1 : 50 12.5 0.085 200 360 0.9 LPR6235-752RML_ 1 : 90 7.5 0.085 275 257 1.6 LPR6235-752SML_ 1 : 100 7.5 0.085 316 230 1.6 1. When ordering, please specify packaging code: LPR6235-253PMLC Packaging: C = 7 ″ machine-ready reel. EIA-481 embossed plastic tape (350 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 (1500 parts per full reel). 2. Inductance is measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent. 3. SRF measured using an Agilent/HP 4191A or equivalent. 4. DC current applied to L1, at which the inductance drops 10% from its value without current. 5. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering. These shielded parts are only 3.5 mm high and 6 mm square. The excellent coupling coefficient (k = 0.95) makes them ideal for use in a variety of applications. They can be used as flyback transformers and step-up pulse transformers. The high Isat and low DCR ratings of these parts provide high efficiency and excellent current handling in a rug- ged, low cost design. Custom inductance values and turn ratios may be avail- able upon request.
