Abstract
A coil assembly having a core and a winding on the core, wherein a contact element electrically connected to the winding is both mechanically clamped and bonded to the core. In an exemplary microcoil assembly having a C-core, a generally U-shaped contact element is bonded to each foot of the core by epoxy and mechanically clamped to the core foot to hold the contact element in position while the epoxy cures. One end of the coil winding is soldered to one of the contact elements and the other end of the winding is soldered to the other contact element. The coil assembly is subsequently soldered onto a printed circuit board. Each contact element may include a pin portion to be inserted into a printed circuit board.
