Patent number: 9490072Abstract: A method for making multilayer ceramic capacitors is described with high voltage capability without the need of coating the part to resist surface arc-over. One design combines a high overlap area for higher capacitance whilst retaining a high voltage capability. A variation of this design has increased voltage capability over this design as well as another described in the prior art although overlap area and subsequently capacitance is lowered in this case.Type: GrantFiled: April 30, 2014Date of Patent: November 8, 2016Assignee: KEMET Electronics CorporationInventors: John Bultitude, James R. Magee, Lonnie G. Jones
