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. 4.3 (0.17) 9.0(.355) 2.5±.5 3 typ IDEA 5.08 LED 1 9.65 IDEA 2.54 LED 2 3.5 min Anode typ 2.54 5.08 2.54 Red or yellow Anode Green Anode + – (Pinout for single color) (typ for bi-color) 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.
