Hi @JRaim.1 ,

In addition to Peter's complete description, we can say the third line, and especially the two last letters/numbers, refer to the specific assembly lot of those samples.

This information is useful at failure analysis level.

Welcome, @JRaim.1, to the community!

the important marking is H3D3, which stands for H3LIS331DLTR.

The first and last lines should only be required if a quality issue arises and the component would need to be examined in detail. Maybe the datecode here is interesting: line 1, 830 = year 2018, week 30.

Regards

Our quality engineers have encountered some problems in identifying the markings.

We would be very grateful if you could explain the meaning of the symbols (line 3) in the attached photo. Is it a data code or a lot number? How can one packing tape contain devices with different markings?
