Depending on where you live and what exactly you were charged with, it's probably either a misdemeanor or a "local ordinance offense/violation" (wording may change depending on location). If you didn't go in front of a judge or plead guilty to a charge (which is what it sounds like), it's probably the latter, in which case no, you don't have to claim it on any application. Even if it is a misdemeanor, it may not show up on a background check depending on where you go and how thorough they check. However, if you want to be safe, just list it with an explanation on the application. It shouldn't hurt your chances much either way.
Keep in mind, I'm not a lawyer (but have had my share of experience with the law) so don't, by any means, rely completely on the information in this post.
Edit - Unless you're on probabtion (maybe even if you are?) you don't even have to disclose the fact that you have a misdemeanor on your record. Though, again, I'm not a lawyer and don't take what I say as gospel.
