摘要： Surface-mountable conductive polymer devices include a conductive polymer layer between first and second electrodes, on which are disposed first and second insulation layers, respectively. First and second planar conductive terminals are 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. In some embodiments, at least one cross-conductor includes a beveled portion through the first insulation layer to provide enhanced adhesion between the cross-conductor and the first insulation layer, while allowing greater thermal expansion without undue stress. In other embodiments, these advantages are achieved by having at least one cross-conductor in physical contact with a metallized anchor pad on the first insulation layer.
