I am just wondering why this Manufactures reel would have different markings on the components? I’ve checked the Mfg. website and there is no mention of any markings on the datasheet. Thank you!
It is likely these different markings are internal traceability related to separate lot codes/batches.
LEDs are made in large batches and then sorted and separated based on what the measured wavelength, brightness and forward voltage is and then grouped into what we call bins.
It takes several manufacturing runs to build enough similar parts to create a bin. Again, I believe what you are witnessing is lot code markings for internal quality/tracability uses.
Thank you Kristof! You’re the best!
