    • A capacitor (10) exhibiting a benign failure mode has a first electrode layer (12), a first ceramic dielectric layer (14) deposited on a surface of the first electrode (12), and a second electrode layer (16) disposed on the ceramic dielectric layer (14), wherein selected areas of the ceramic dielectric layer (14) have additional dielectric material (18) of sufficient thickness to exhibit a higher dielectric breakdown voltage than the remaining majority of the dielectric layer (14). The added thickness of the dielectric layer (14) in selected areas allows lead connections (22) to be made at the selected areas of greater dielectric thickness while substantially eliminating a risk of dielectric breakdown and failure at the lead connections (22), whereby the benign failure mode is preserved.
    • 表现出良性破坏模式的电容器(10)具有第一电极层(12),沉积在第一电极(12)的表面上的第一陶瓷电介质层(14)和设置在第一电极层 陶瓷介电层(14),其中所述陶瓷介电层(14)的选定区域具有足够厚度的附加电介质材料(18),以显示比所述电介质层(14)的剩余大部分更高的介电击穿电压。 在选择的区域中增加的介电层(14)的厚度允许在更大介电厚度的选定区域处制造引线连接(22),同时基本消除引线连接件(22)处的介电击穿和故障的风险,由此 良性失败模式得以保留。

    • A multi-layer capacitor (10) includes an anode (12), a cathode (16), a dielectric material (20), a first endcap (22A), and a second endcap (22B). The anode (12) and cathode (16) are formed of one or more layers (14A, 14B) of interlaced conductive material. The dielectric material (20) is interposed between each of the layers (14A, 14B) of the anode (12) and the cathode (16). The first and second endcaps configured to interconnect each of the layers (14A, 14B) of the anode (12) and cathode (16), respectively. The endcaps are formed of conductive nano material. A method of forming an endcap of a capacitor (10) configured to interconnect one or more layers (14A, 14B) of conductive material includes the step of applying conductive nano material (34) to exposed conductive surfaces of at least one of an anode (12) and a cathode (16) of the one or more layers (14A, 14B) of conductive material. The method also includes the step of exposing the nano material to a source of energy effective to initiate self-sintering of the nano material.
