Capability statement
Critical dimensions are confirmed individually.
Dimensional capability is established against the capacitor-can drawing. Critical diameters, length or interface features are evaluated individually rather than assigned one blanket tolerance.
*Not a universal tolerance for every feature. Final capability is confirmed through drawing review, development trials and the agreed inspection plan.
