•0.125 in (3.18 mm) ±0.010 (±0.25 mm)

Features and Benefits:
•Available with a thin, acrylic, proprietary electrically conductive, pressure-sensitive adhesive (PSA) backing
•Sheet stock without adhesive backing has an indefinite shelf life (with PSA shelf life is 1 year)
•For part numbers where two temperature values are shown, the first represents max. operating temp. for conformance to MIL-DTL-83528 and the second value represents the practical limit for ex posure up to 1000 hrs. (compressed between flanges 7-10%). Materials with single values conform to both definitions..
