NSN K375-5C

A washer having a centrally located hole with a solid or laminated cross-section and two flat parallel bearing surfaces. The hole must be 75 percent or less than the largest dimension and the bearing surface finish is greater than 32 microinch (0.8 micrometer). The thickness cannot exceed 25 percent of the largest outside dimension. When the largest outside dimension is less than 1/4 inch or 6mm, the thickness must be 0.006 inches (0.15mm) or greater and for items 1/4 inch (6mm) or larger, the thickness must be 0.016 inches (0.4mm) or greater. The maximum tolerance is applied to dimensions and used as a determining factor. Items with separable lamination use shim. For items fabricated from ceramic or electrically rated materials by specification or industry standards use insulator (1), washer. Excludes:disk, valve, graphite impregnated and lubricated items.

55.0 maximum equivalent resistance value in ohms, 0.310 inches minimum and 0.330 inches maximum diameter, series resonance circuit resonance, 0.7 milliwatts minimum and 0.9 milliwatts maximum drive level rating, 0.190 inches minimum and 0.210 inches maximum center to center distance between terminals.
