I don't think it's anything like that simple unfortunately - there are a = huge number of variations between manufacturer and types of components - I don't think you can = produce a meaningful 'avarage' Low-end prices <1000 are very often distorted - some makers have obvious = policies of not wanting to deal with small numbers (100x =3D 2x the 10x price for example), and = different types of parts will have different economies of scale - e.g. SM parts tend to come on reels,= so anything below a reel multiple will be priced very differently depending on the distributors' = attitude to splitting reels. =46or a part that is manufactured by the zillion, above a certain volume = it doesn't actually cost much less to make/distribute 1million or 10 million - the definitionof = 'zillion' will of course again depend on the type of part.=20 You could maybe do an avarage within certain component type catagories = that might be vaguely meaningful though, especially for general-purpose parts.=20 =20 -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
