Part Number: LM2903

There are differences in marking font format, and there are also slight differences in the material plates. Some material plates are of two colors, while others are of one color. Could you please help confirm the reason

Thank you

Hello,

The LM2903 is a very high volume device and is assembled in several assembly sites. The leadframe used can be different depending on the sites capabilities.

So there are several finishes that are possible. Please see the "Lead Finish/Ball Material" in the "Ordering and Quality" section of the product folder:

If you order the LM2903DR, you could get either finish.

You have to order the "G4" or "G3" versions to ensure the finish.
