Note:
The power derating curve is a guidance based on a con-
servative design model. The OARS is a solid metal alloy
construction that can withstand signifi cantly greater operat-
ing temperatures than conservative design models permit.
The resistive alloys can withstand temperatures in excess
of 350°C. Therefore, the system thermal design is a more
signifi cant design parameter due to the heat limitations of
solder joints and/or circuit board substrate materials. Refer to
additional information below.
The thermal image (not a simulation) to the left is of an OARS
10 mΩ running at 2 Watts, which exceeds the 1 Watt conser-
vative model. Notice the hotpsot is nearly 200°C, but the sol-
der joint is approximately 65°C (FR4 is rated for 130°C). The
unique construction of the OARS isolates the hotspot from
the circuit board material preventing damage. Additionally,
the thermal energy is dissipated to the air instead of being
conducted into the circuit board potentially causing a nearby
power component to exceed its rating.
The standard test circuit board consists of a four layer FR4
material with 2 ounce outer layers and 1 ounce inner layers,
which is typical of many industry designs. Contact IRC for
more details or for other thermal image test data for specifi c
resistance values and power levels.
