Document 1005F-1 Revised 09/08/15 Document 1005F-1 Dimensions are in inches mm 1 4 L1 L2 Coupled Chip Inductors PFD2015 For Flyback, SEPIC, Zeta and other applications With a footprint of 2.2 × 1.45 mm, the PFD2015 is Coil- craft’s smallest shielded coupled inductor. It is ideal for use in a variety of circuits including flyback, multi-output buck, SEPIC and Zeta. These inductors provide high efficiency and excellent current handling for parts this small. They can also be used as two single inductors connected in series or parallel, as common mode chokes or as wideband transformers. 0.059 1,5 max max0.060 1,52 0.017 0,432 0.044 1,118 0.028 0,711 0.016 0,406 0.022 0,559 0.054 1,36 0.014 ±0.003 0,356 ±0,076 0.010 0,25 Recommended Land Pattern max0.090 2,29 4 3 1 2 4 3 L1 L2 + + D C C Typical Flyback Converter VOUT VIN SW D D C C SW Typical Buck Converter with auxiliary output VOUT VOUTAUX VIN Typical Zeta schematic VOUTVIN L1 L2Q C1 CC D Typical SEPIC schematic VOUTVIN L2Q CC D

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. Fac- tory order only, not stocked (7500 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/HP8753 or equivalent. When leads are connected in parallel, SRF is the same value. 5. Leakage inductance is for the primary winding with the secondary windings 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 40°C temperature rise from 25°C ambient. See temperature rise calculation. 8. Maximum current when applied to one winding that causes a 40°C temperature rise from 25°C ambient. See estimated temperature rise calculation. 9. Electrical specifications at 25°C. Refer to Doc 639 “Selecting Coupled Inductors for SEPIC Applications.” Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
