T-1, (3-mm) Round, Bi-level PCB Mount LED Indicator, G478B Series www.ledidea.com The G478B 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. 4.3 (0.17) 9.0(.355) 4.0 3 typ IDEA 5.08 LED 1 9.65 IDEA 2.54 LED 2 3.5 min Anode typ 2.54 Red or yellow Anode 5.08 2.54 Green Anode + – (Pinout for single color) (typ for bi-color) Specify part desired as follows: G478B/Order Code LED1 + Order Code LED 2 For example: “G478B/H+G” designates an assembly with a red LED on top and a green LED on the bottom. “G478B/(H+G)-RL” designates the same assembly with leads reversed.
