When ordering, please specify packaging code: NA5889-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 Dot above pin1 ready) or with leader and trailer ( 25 charge). B = Less than full reel. In an effort to simplify our part numbering system, Coil- craft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D. 0.500 max 2. Inductance measured at 200 kHz, 1.0 Vrms, 0 Adc. 12,70 3.
