Hello,
I have found myself without a spec sheet but a supply of working 940nm IRs. I have been able to identify the forward voltage (1.25v) and for now have chosen a low value resistor (270 ohms). From this I can determine the current through the LED. I would like to know the LEDs maximum forward amperage though rather than experimenting with the LEDs and destroying a few. The second question is what % of that maximum forward current should be its everyday use e.g. 70%?
Thank you.
