Case marking of KMZ41 chips

[vladz]

Is there somewhere a links to the description of the marking on the case of KMZ41 chips ?

Magnetic field sensor|NXP 

How to understand (decode, decrypt) marking lines on the case of KMZ41 chips ?

For example what is 8005, D102 ; n440, n204 ?

Can the number on the bottom line after the letter "n", have a four digits# ?

Many thanks, Tomas.

I still have my chips with this marking.

The last line of the four characters after the letter "n".

Immediately after the letter "n", it seems G rather than number 6.

nG503

What is the combination?

Hi Vladimir,

The letter "G" represents the RoHS compliance (RHF-2006) status:

Hi Vladimir,

The device marking of the KMZ41 is as follows:

1st  line:               Product name   

2nd  line:              Shortened diffusion batch number (2 digits) plus shortened assembly batch number (2 digits)

3rd  line:               Assembly center (n for Bangkok, sole assembly center for KMZ41)

                             1 digit for the year (4 = 2014)

                             2 digits for the work week (40 = week 40)

Best regards,

Tomas
