Ceramic resonators have looser frequency tolerances (1% or so) than
the average crystal, and they usually need larger capacitors in the
oscillator circuit.  Some are packaged with the appropriate
capacitors built-in.

They often come in little plastic boxes, but sometimes look almost
like capacitors.
