When ordering, please specify packaging code: WB25-1SLD Packaging: D = 13 machine-ready reel. EIA-481 embossed plastic tape (500 parts per full reel). B = Less than full reel. In tape, but not machine ready. To have a leader and trailer added ( 25 charge), use code letter D instead. 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. 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 max imbalance. 6. Electrical specifications at 25C. Measurements are referenced to 50 Ohms. Refer to Doc 362 Soldering Surface Mount Components before soldering.
