    SMT Capacitor question, plz help!

    Iīm projecting a Board with a bit of capacitors SMT CASE A like in the PDF above:
    http://www.avx.com/docs/Catalogs/taj.pdf

    The problem is that on ORCAD file donīt have the PIN of Cathode and Anode of the Capacitor. When i create the NET list and use on Power PCB occurs a error like:

    *Not valid pin name for part type P
    R9.1 C61.1 C19.P C33.1 C62.1 C63.1 C34.1 C36.1

    Of course, C19.P donīt exist. But when i edit the part of C19 i donīt know with one (pin 1 or 2) i put in Cathode and Anode.

    Does it have any standard, like pin 1 for Anode (+)? Can anyone help me?
    :D

    SMT Capacitor question, plz help!

    Although I do not know Orcad etc, can you identify them on the symbols etc with a + mark?
    Please do not PM me questions that are better asked in the PCB forum :)

    only from the symbol in schematic, we should make decision of which pin is positive and negative , but in your case, better to check with the value of the cap, as always caps whichevey the value greater than 1 UF , are polarised, ans less than this are non-polarised
