    Simple question...Do ceramic capacitors have to be oriented in a
    specific way like electrolytic do? positive/negative ??? Any help would
    be great, Thanks, Lucas

    Complex answer:For shielding it can be important to
    know which connection is to the top and which to the
    bottom,Some caps have a line along the side,that shows
    it is connected to the outside(with a wound cap),
    or top(with a layered one).
    But it is not important for the dc +/- orientation.

    Beyond that, ceramic *disc* capacitors are symmetrical, so it truely doesn't
    matter.

    In very critical applications, like HF amplifiers and stuff, it _might_
    make a difference as to which side of the capacitor is closer to what,
    physically. The reason being the capacitance between each plate and
    its surroundings.

    But electrically, the cap itself couldn't care less.

    There are non-polarized caps, like tubular, where the "outside foil"
    is marked, and usually that's connected to the side of the circuit
    with the less potential to ground, but again, that's mostly about
    strays and parasitics.

    Cheers!
