LED Indicator, J478B Series
The J478B is a popular indicator in LAN hubs and network controllers. Designed to save panel space, the assembly measures just over 4.3 mm(0.170") in width. Long arrays should be located on a pitch of 4.4 mm(0.173") to avoid crowding and tolerance build-up. This series can also be supplied with pinout reversed from that shown by adding "-RL" to the order code of the part number.
Specify part desired as follows:
J478B/Order Code LED1 + Order Code LED 2
For example: "J478B/H+G" designates an assembly with a red LED on top and a green LED on the bottom.
"J478B/(H+G)-RL" designates the same assembly with leads reversed.
