Part Number: UC3638

Hello,

Could I get the tolerance for the following dimensions (see highlighted image)?

Need the Min/Nom/Max for the project I'm working on.

Thanks!

Hey Eatone,

Unfortunately we don't have this exact data as it is a very old part our team inherited. I recommend using -25% of the MAX value given as the minimum.

Or can you open other datasheets with this package and see if any of their Mechanical Drawings pages have been updated with more information: https://www.ti.com/packaging/docs/searchproductbypackage.tsp?orderablePartNumber=&packageDesignator=N&pinCount=20&results=results#resultspage

Best,

Jacob

Hey Jacob,

Thanks for the response! Would you recommend a +/- 12.5% for tolerances of the .010" nominal lead thickness value as well?

Best,

Eatone

Hey Eatone,

I would recommend ±15% for the lead thickness, but 12.5% should work as well.

Best,

Jacob
