Hi, I wish to use the WSHP2818R0500FEA current sense resistor from Vishay in a design. I created a new symbol in my libraries using the R_Shunt base symbol, and simply named it WSHP2818R0500FEA.
However when I use the part in a schematic, I find that the MPN is too long in the sheet and irrelevant for quick electrical analysis. I would rather like to see “50mΩ 1%” instead of the long MPN, but still see the full MPN in the library editor. So I modified my symbol in the library to hide the symbol name (WSHP2818R0500FEA), and added a new value field called “Key Parameters”, having the value “50mΩ 1%”. Now this would solve my problem. However when I wanted to create an alias for a similar resistor, I realized that my new value field was also copied, and could not be modified independently modified from the one of the original component. So it now appears that I won’t be able to use this approach with alias, and I am stuck with using long MPNs to differentiate alias. Does anyone also encountered this problem? A solution for this would be to have the liberty of using independent value fields for alias.
