MOTM

Hi everyone,

I'm getting ready to make a purchase of 1% resistors from Mouser.  I 
have a vague recollection about seeing some comments on ROHS parts 
shelf-life, and was wondering if anyone could elaborate a bit for me.  
My concern is if I buy a couple hundred bucks or so worth of 
resistors, are they going to be unusable if I don't solder them into a 
board within a year or two?  Can this be stalled a bit by storing the 
parts in something like a zip-lock bag?  If there is a usable shelf 
life, can the part leads be re-tinned?

Thanks!

Regards,

Phil Peery
