What kind of timer/delay would I use for this application?

I need a timer that will complete a circuit when sent a signal and then shut off after 30 seconds or so.
  • It can be no larger than 1/2" diameter and 1" long.
  • It doesn't need to be programmable or adjustable.
  • It will use DC voltage -- probably 3V.
I know these are available, but I just can't find them when I search. Maybe they're called something else. (I'm not well versed in electronics.)
