Schaffner IEC line filters were used on HP test equipment and I am aware that vendors selling substantial quantities of "new old stock" HP gear find that the Schaffner filters invariably fail in the first week of operation after coming out of storage.

My personal experience with the filters is only in Australia where the line voltage is 240 to 250V. However, I have been told that Schaffner filter failure is just as common in the USA with its 110V.

It appears that the failure mode is not at all related to the filter's operational hours.
