I'm not sure of the exact failure mechanism, but we had two fail within 10
minutes even when protected with a Terry filter.  We were testing them at
500 pps in a worse case scenario..  The same circuit ran for 2.25 hrs
continuous at 120 pps without any problems on the same model xmfr --- all 3
used in the test were new units.
