When ordering, please specify packaging code: FA2925-ALD Packaging: D = 13 machine-ready reel. EIA-481 embossed plastic tape (175 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ( 25 charge). B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change Dot above pin1 the last letter of your part number from B to D. 2. Inductance is for the primary, measured at 200 kHz, 0.2 Vrms, 0 Adc. 3. Ipk is peak primary current drawn at minimum input voltage. 0.500 4. DCR for the secondary is per winding. max 12,70 5. Leakage inductance measured between pins 1 and 2 with all secondary pins shorted. 6. Turns ratio is with the secondary windings connected in parallel. 7. Output is with the secondary windings connected in parallel. 0.004/0,10 0.039 8.
