Wouldn't that be far more dependent on particle size? Micrometeorites are going to reach terminal velocity fairly quickly, and that's largely going to be based on particle size and density, rather than original velocity.
Sand-grain-sized micrometeorites (or the sand-grain-sized surviving fragments of larger meteors) will have a terminal velocity of on the order of a metre per second or so.
