Surface flashover resistant capacitors and method for producing same

摘要

A surface flashover resistant multilayer ceramic capacitor. The capacitor has a plurality of layers of dielectric material and a plurality of electrodes disposed between the layers of dielectric material. End caps are located at either end of the capacitor and are connected to one or more of the internal electrodes. A coating comprising one or more insulative layers is applied to the outer surface of the capacitor and selected portions of the coating are subsequently removed. The coating of insulative layer is a polymer, and specifically a poly-para-xylylene. The insulative coating is applied through a vapor deposition process. The selected portions of the insulating layer are removed by laser ablation.
