T-1, (3-mm) Round, Bi-level PCB Mount
LED Indicator, J378B Series
The J378B is one of the most popular indicators in LAN hubs and network controllers. Designed to save panel space, the assembly
measures just over 4.3 mm(0.170") in width and can be CMOS driven to save components. 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 add-
ing “-RL” to the order code of the part number.

For example: “J378B/G+Y” designates an assembly with a green LED on top and a yellow LED on the bottom.
“J378B/(G+Y)-RL” designates the same assembly with leads reversed.
