TO-46 Package With Lens

This device is designed for Ethernet

and general applications and offers an

excellent price/performance ratio for

cost-effective solutions. Since it oper-

ates at low drive current, it generates

minimal heat — reducing cooling

requirements in systems employing

large numbers of LEDs.
