Hard Anodized Aluminum

RoHS Compliant

A unique hardcoating process is employed which is optimized for diaelectric

capabilities. This process yields a uniform .025mm (.001") minimum coating, which is

an integral part of the base aluminum insulation. The .51mm (.020") thick aluminum

provides adequate support for the anodized coating for maximum heat transfer and

superior performance.

These durable hard anodized insulators have a high thermal conductance and a

minimum breakdown voltage of 400 volts DC through two layers of hard anodized

coating (per ASTM B110 test procedures).

Notes:

Dimensional tolerances and hole diameters are

± 25mm (.010"), angularity is

flatness is .10mm (.004"). Total Indicator Reading unless otherwise specified. All

washers are .51mm (.020") thick unless otherwise specified. The asterisk symbol

(*) on the dimension drawing denotes racking location.
