Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
151 words
A passive electric component suitable for surface mounting comprising: an elongated supporting member carrying a layer of electrical component material and having a pair of conductive termination areas for said layer at the circumferential perimeter of said supporting member proximate respective opposite end faces of said supporting member; and surface mounting means comprising a pair of electrical connection elements at opposite ends of said supporting member respectively surrounding the circumferential perimeter of said supporting member and being in electrical contact with said pair of conductive termination areas, said electrical connection elements having open outward ends substantially flush with the respective end faces of said supporting member, whereby said electrical component has an overall length measured between the opposite open outward ends of said electrical connection elements, and the area of the portion of said electrical component which is free of said electrical connection elements is maximized relative to said overall length.
Claim 2
Dependent Claim
