    Part ID question

    Hi all,
    Ran into a part I don't know the OEM or type.
    Attached is a photo.

    Not the big orange caps, but the little ones near the center, that look like they were intended for through hole pc mount.

    This is part of a modulator for a Harris broadcast transmitter.

    Thanks in advance.

      I see the Orange Drop and CDE silver mica caps, but not sure about these ones.
      Label is 4.7M or 47M 50V which is too small in value for film caps?
      It has 3 camel humps like maybe ferrite bead inside, square base. Hmmm.

              Pete,
              Apparently the prior maintainer of this transmitter went out of his way to screw this thing up. So most anything can happen.

                STJ and company,

                I passed on your answer and the others to Earl, one of my shop mates who is doing the actual work.
                Was able to find a vendor for the parts.

                Many thanks to all for the heads up.

                  They look similar to these Sprague .047uf 50V Monolithic Ceramic Capacitors

                    I think they are Sprague disc capacitor, Z5U 50V 20% nothing special.
                    A 0.047uF one is 7CZ5U473X0050DC
