Hi ST Team,

Can you share the Marking code specification for the product: LPS22DFTR ?

Thanks, 

Danny.

TR is just tape-n-reel delivery

The LPS22DF is marked with the letter F, which can also be found on the packaging bag.

Hi Tesla and Peter,

Good day,

Thank you so much.

We received the parts .The all top side marking are F/ 104.

Can you share the doccument ? we need to add it to the System for incomming check and ISO Audit

Thanks.

The lack of marking information in the data sheets has been a persistent source of questions.

On the Need-to-Fix list, it needs to be a lot higher than making the Web Site prettier.. Surprised there's not an ISO requirement/expectation on ST's end

The number might be a YWW date code, would check the packaging, and trace info.

Correct, the marking of the LPS22DF is:

• F (stands for the LPS22DF and packaging options like LPS22DFTR)
• YWW (in your case 104 = 2021, wk 4)

But what was engraved on the item would be this, how can I evaluate this mark code? there is no such information in the datasheet.
