Power Derating
The typical power derating curves are based on conservative design concepts that extend from ? lm
based products. The OAR is a solid metal alloy construction that can withstand comparably greater
operating power levels than conservative design models permit. Typically the resistive alloys can
withstand temperatures in excess of 300°C. Therefore, system thermal design considerations are a more
signi ? cant design parameter due to the heat limitations of solder joints and/or circuit board substrate
materials.

The Surge current charts are approximations of the capabilities of the OAR product and should not be
used to the exclusion of actual testing. The relative high surge currents depicted in the charts are as a
result of the robust all metal welded construction and the heat carrying capability of metal. Additionally
the OAR resistive wire provides large relative cross section for current ? ow as compared to other resistor
technologies, such as thin ? lm, thick ? lm, or metal strip.
