    hai
    all i am designing and developing pulso oximeter...for which i need and 1:1 isolation transformer...the secondary winding provides an 8v ac output with a current capacity of 500mA.
    here by i am sending you the pcb layout the tranformer should exactely fit into the empty square area which is denoted by (SS). which is provided with 4 holes.
    please help me which tranformer i have to choose and what wl be the cost of that transformer.

    Ummm...this is kind of a technical forum, not a home shopping forum. Most people won't find your question intriguing enough to answer. More likely, the answers you'll get are like, search www.mouser, or Digikey, or Jameco. However, you did not say what country you are in, so we can't guess which suppliers you can get to.

    How about an accompanying schematic? What frequency AC is supplied to the transformer primary?

    In the end it will probably be a custom wound transformer, not an off-the-shelf component.

    Normally you design PCB and the hole pattern for all the parts after you selected all the components.

    There are plenty of transformer companies out there.

    KMoffett is correct, you need to give up the specifics of your requirement.
