NOTES:
1. Transformers are shipped in trays unless Tape & Reel packaging is specified by adding the suffix
“T”
to the part number (i.e. BX2373JBT).
2. Chip Side DCR Measurements:
Schematic A
= (8-5) with (6-7) shorted;
Schematic B
= (8-6) with (5-7) shorted.
3.
B2517J
is approved for ADSL+ Applications only.
