SFH 4050-Z SMARTLED - polarity?


#1

Hi everyone,

I purchased a batch of SFH 4050-Z Osram Opto SMARTLED IR emitters for an eye tracking project.

So as I dont stuff up the polarity how do you tell the + - or A C direction for these minute little emitters.

P/N 475-2864-1-ND

MFG Part number: SFH 4050-Z Part name: Emitter IR 860NM 100MA SMD

The clipped corner of the LED is the anode side. They actually leave that information hard to find on the data sheet, but you can see the clipped corner should be towards the sprocket holes on the tape which is the anode of the LED.
