Hi all,

We have DC/DC supplies on boards which include flat ferrites mounted side to 
side (i.e. the PC conductors go through the ferrites)
When we test the boards for NEBS, including 10 cm drop the ferrites tend to 
break (Interestingly during HALT or other vibrations the ferrites survuve 
well)

Do you know this phenomenon? Is there some way to protect the ferrites?

thanks in advance for your inputs,

regards,
Moshe
