These vintage Fluke resistor network chips are one of our smallest and most interesting to look at under a magnifying glass. Yet their bold, shimmering rectangles make them just as attractive at a glance.  Manufactured for the Fluke Company, they were destined to be part of their renowned electronic testing equipment.  3/8" x 5/8" ceramic chip with silver colored square bead. 1 1/2 long from top of ear wire to bottom of chip. Sterling silver ear wire.
