When ordering, please specify packaging code: GA3372-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 ma- chine 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 Dot above pin1 ordering, simply change the last letter of your part number from B to D. 2. Inductance measured at 250 kHz, 0.7 Vrms, 0 Adc. 3. Peak primary current drawn at minimum input voltage. 0.500 max 4. DCR for the secondary is with windings connected in parallel. 12,70 5. Leakage inductance is for the primary and is measured with the secondary shorted. 6. Turns ratio is with the secondary windings connected in parallel. 7.
