1. When ordering, please specify a packaging code:
WB3040-SMLD
D = 13″ machine ready reel. EIA-481 embossed plastic tape (500 parts per full reel). Quantities less than full reel available: in tape (notmachine ready) or with leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes.
When ordering, simply change the last letter of your part number from B to D.
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.
