1. 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. Measurements are referenced to 50 Ohms.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
