JS: Based upon the (ONLY!) two I have ever seen in real life, they are
WONDERFULLY engineered and built, so I suspect they will function at their
"specification limits" just fine for years.

But, per the "white paper" that comes with them, you must HEAT-SINK any used
for more than 1.0 amp per winding. This would not ONLY mean bolting them to
a solid aluminum heat-sink, but also using properly-applied "heat-transfer
compound" (usually a berillium-based whitish grease-stuff), and proper
mechanical discipline.
