When ordering, please specify termination and packaging codes: WBC4-4LC Termination: L = RoHS compliant tin-silver-copper (95.5/4/0.5) over silverpalladium-platinum Special order: S = non-RoHS tin-lead (63/37). Packaging: C = 7 machine-ready reel. EIA-481 embossed plastic tape (750 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 C instead. D = 13 machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (2500 parts per full reel). 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 maximum imbalance. 6. Electrical specifications at 25C. Measurements are referenced to 50 Ohms. Refer to Doc 362 "Soldering Surface Mount Components" before soldering.
