OPA2132: For ordered part number OPA2132UA, physical part marked with "U K" not "UA"

Part Number: OPA2132

For ordered part number: OPA2132UA

The physical part came marked with a "U K" instead of OPA2132UA.

Wanted to know if the K is for something else.

Tried looking through the datasheet to find marking details but i could not find.  Please advise.

    Hello Brian,

    The "K" to the right of the 2132U marking is the assembly location indicator. The "A" in the upper left corner is the grade marking indicating that it is an "A" grade device. Thus, the top marking indicates that the device is an OPA2132UA.
