When ordering, please specify packaging code: WB-SLD Packaging: D = machine-ready reel. EIA-8 embossed plastic tape ( parts per full reel). B = Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($ charge), use code letter D instead.. Impedance ratio is for the full primary winding to the full secondary winding.. Inductance measured at khz,. V, Adc on an Agilent/HP 9 or equivalent.. DCR measured on a micro-ohmmeter.. DC imbalance is the imum difference in current measured at pins and with the source at pin. Inductance drop is % at imbalance.. Electrical specifications at C. Measurements are referenced to Ohms.
