    I'm looking for some help in understanding the markings on capacitors in
    general.....
    For example:
    104 = uf (Normal Ceramic Disc type)
    N1K63
    1NK63
    etc.etc.etc....

    Please let me know of any webpages that have a good cross reference chart.

    Thanks Colin.
     
  2. Ceramic capacitor values are often given in pF using a system similar
    to the resistor colour code - except that the actual numbers are
    marked on the capacitor.

    Using this system, your "104" capacitor is 1, 0, and four more zeros -
    100,000 pF, or 100 nF, or 0.1 uF

    A 33 pF capacitor would be marked "330", and a 330 pF capacitor would
    be marked "331"

    Other markings would indicate tolerance and temperature
    characteristics.

    Colin Lowe engraved with a +2 athame:
    10 + 4 zeros pf = 100.000 pf = 0.1uf

    Other markings are often for tolerance.
    I've found a general capacitor site at
    http://www.uoguelph.ca/~antoon/gadgets/caps/caps.html.
