RX Auto Transformer
(See Table)
1. R1-R4 = 75 Ohms, 1/16 W, 5%
2. C1 is an optional 1000pF, 2KV de-coupling capacitor
which is included with the -C suffix.
3. The auto transformer is not i ncluded. Th e R1/R 2 center tap termination is
made directly to cable side of T1/T2.
Notes: 3800
General Features:
-Single Port Through Hole
-Multiport:
1 x 4, 1 x 6, and 1 x 8
-UL Recognized Component;
File # E203973
-Models to Support Most Popular
Phy Chips
-Meets IEEE 802.3 and ANSI X3.263
Requirements.
-Includes integrated LEDs. LED signal
leads are isolated from the Ethernet
signal leads to reduce EMI
and crosstalk.
-Signal routing is designed for NIC
applications. See datasheet
RJ7XX-Schematic 7H2 and datasheet
RJ7XX-Schematic 7H5 for Hub signal routing.
-Other signal routing is available. Please
contact the factory at the numbers listed
below.
-Standard LEDs are green. For other
LED options, see the
RJ7XX & RJGn-7XX - LED Options Datasheet.
