Description
The OPF371 series LED consists of a low cost plastic cap LED, pre-mounted and aligned in an SMA receptacle. This configuration is designed for PC board or panel mounting. Includes lock washer and jam nut, two 2-56 screws, and a dust cap.
The LED’s are designed to interface with mulitmode optical fibers from 50/125 to 200/300 microns.

Notes:
(1)RMA flux is recommended. Duration can be extended to 10 sec. max when flow soldering.
(2)Graded index fiber, 50 μm core, N.A. = 0.20.
(3)To convert radiant power output to dBm, use the following expression: dBm = 10 log (μW/1000).
(4)Derate linearly @ 1.0 mA/o C above 25o C.
(5)Prebias @ 5 mA current.
LED Burn-in
All LED's are subject to 100% burn-in testing. Test conditions are 96 hours at 100 mA continuous current in 25o C ambient.
