Abstract
Surface-mountable devices include a conductive polymer layer between first and second electrodes, on which are disposed first and second insulation layers, respectively, with first and second planar terminals on the second insulation layer. A first cross-conductor connects the second electrode to the first terminal, and is separated from the first electrode by a portion of the first insulation layer. A second cross-conductor connects the first electrode to the second terminal, and is separated from the second electrode by a portion of the second insulation layer. At least one cross-conductor may include a beveled portion through the first insulation layer. Alternatively, at least one cross-conductor may contact an anchor pad on the first insulation layer, the anchor pad having a small area relative to the areas of the terminals. Enhanced adhesion between the cross-conductor(s) and the first insulation layer is provided, while allowing thermal expansion without excessive stress.
