PRODUCT INFORMATION
840nm
1A239
High-Performance LED
Datacom, General Purpose
This device is designed for Ethernet and general applications and offers an excellent price/performance ratio for cost-effective solutions. Since it operates at low drive current, it generates minimal heat -- reducing cooling requirements in systems employing large numbers of LEDs.
