<p>A generally prismatic package (1) for an electrical device in the form of supercapacitive element (2) having an electrical property with a predetermined value. Package (1) includes an insulating element in the form of a generally rectangular-prismatic liquid crystal polymer (LCP) housing (3) for supporting element (2). More specifically, element (2) is mounted to the insulating element such that, following surface mounting of element (2) to a substrate, in the form of a printed circuit board (not shown), the electrical property remains within a predetermined tolerance.</p>
