 Components can be supplied mounted on carrier tapes.Surface mount components can be about one-quarter to one-tenth of the size and weight of through-hole components, and passive components much cheaper.However, prices of semiconductor surface mount devices (SMDs) are determined more by the chip itself than the package, with little price advantage over larger packages, and some wire-ended components, such as 1N4148 small-signal switch diodes, are actually significantly cheaper than SMD equivalents.
