In tape, but not machine ready. To have 4 3 a leader and trailer added ( 25 charge), use code letter C instead. 66 11 B D D = 13 machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (2500 parts per full reel). PriP22Sec ri Sec 2. Impedance ratio is for the full primary winding to the full secondary winding. 3. Inductance measured at 100 kHz, 0.1 V, 0 Adc on an Agilent/HP 4192 or equivalent. 4433 4. DCR measured on a micro-ohmmeter. 5. DC imbalance is the maximum difference in current measured at pins 1 and 3 with the source at pin 2. Inductance drop is 15% at maximum imbalance. 6. Electrical specifications at 25C. Measurements are referenced to 50 Ohms. Refer to Doc 362 Soldering Surface Mount Components before soldering.
