T-1, (3-mm) Round, Bi-level PCB Mount
LED Indicator, G78B Series
www.ledidea.com
The G78B 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. Long arrays should be located on a pitch of 4.4 mm(0.173") to avoid crowding and tolerance
build-up. For long arrays, also investigate our G784B series which is designed to replace 4 assemblies and is matched to the G78B in
height, depth and lamp location.

Specify part desired as follows:
G78B/Order Code LED1 + Order Code LED 2
For example:
“G78B/H+G” designates an assembly with a red LED on top and a green LED on the bottom.
“G78B/(H+G)-RL” designates the same assembly with leads reversed.
