SMD orientation


Jack Purdum
 

There seems to be some confusion about how U2, the SMD part, is oriented on the PCB. I've attached a photo that should clear that up.


 

Your BOM calls out a MAR-3SM+.? Most of what I am finding online is a MAR-3SM.? Do you know if the + designates anything important?? I didn't see anything that looked meaningful in the data sheets I could find.
thanks

You should be ok with either, but the MAR-3SM is considered obsolete now.

Jack,

It might be easier for us to search for all the posts related to your board if we agree to suffix them the subject like with "w8tee vfo" or something. that way, the those how come in later will be able to search and read these posts sequentially.

just a suggestion, it will involve reposting the questions under a new subject line, but the categorization will be worth it.?

the other way is to add an easter egg '#w8tte-vfo' in the reply itself. those who search for this term will find these posts. it is a way to hashtag within the posts of this group.

Doug,

?

The ¡°+¡± sign designates a part that is ¡°RoHS¡± (lead free) compliant.? Parts without the ¡°+¡± sign have the same functionality.
