The right choice of insulator and metal film are necessary, but so are test procedures. This is not a "defect" issue per se, as any capacitor dielectric will break down if stressed with a sufficiently high voltage. The issue is how well the dielectric + conductor film system heals itself after the breakdown event.With the best of design intentions and knowledge, and the best uniformity of materials, a capacitor made on a manufacturing line that does not perform testing for the self-healing requirements would be at risk for failure in a highly dangerous application. Whoever makes Auricaps may well use the test methodology as well as a self-healing design, but if they don't get third-party approval and mark the capacitors as X- or Y-rated, then how are we to know?
