LM2831: LM2831YMFX/NOPB, Tolerance of tape width and component pitch

Kento Sato

Part Number: LM2831

Hi team,

Could you let me know the tolerance of tape width and component pitch of LM2831YMFX/NOPB?

We can see the tape specification on P.28 of data-sheet, however we can't see the tolerance.

Thus we'd like to know that.

Best regards,

Kento

    Hi Kento,

    what is mean of "tolerance of tape width and component pitch", you can get the specific package information from datasheet P.33~P.38.

    Best Regards,

    Kevin

    Hi Kevin-san,

    Thank you for your support.

    I saw the data-sheet.

    I mean tolerance is the precision(+-).

    I can see the tape width and component pitch, I'd like to know the precision(±).

    Best regards,

    Kento

    Hi Kevin-san,

    Thank you for your support.

    I accidentally answered "Resolved", So I have another question. 

    I'd like to know the precision(+-) of this table as below, especially P1(mm) and W(mm).

    Could you let me know that?
