When ordering, please specify a packaging code: WB3040-SMLD 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 tested at 100 kHz, 0.1 Vrms, 0 Adc. 4. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
