摘要

The coil (1) is cylindrically wound as a single layer of wire with no magnetic core or yoke. The wire is of sufficient dia. for stability and self-support with its ends (2,3) in a tangential plane and stripped of insulation for mounting and bonding on a printed circuit board. On top of the coil an earthing disc (4) is provided with faces parallel to the plane of the ends for ease of handling by automated assembly machines. The dimensions of the disc are somewhat smaller than the axial length and breadth of the coil.
