PWB reference designators

prev: pwb_layers.htm -- next: pwb_test_fixture.htm

(also called PCB reference designators)

You've seen circuit boards with cryptic little white words like "R129" and "C17". Those are the reference designators. You may already know what the "R" and "C" stand for -- but what are these parts labeled "Z1" and "Z2" ? And when I'm making a new board, how should I label this polyfuse ?
