Is it common for military electronics to have a self-destruct feature to protect technology secrets?

E.g., when damaged beyond repair or abandoned in a hasty retreat, the hardware could ignite a little thermite to incinerate the electronics boards.

One of the stealth helicopters used in the assassination of bin Laden was so destroyed, but a part of the tail was left behind.

I used to have some old (tube-based) test equipment that included instructions on exploding it with a grenade in the event that it had to be left behind. The grenade was not built in, however.
