Examples
DIP packages have been mostly displaced by surface-mount package types, which avoid the expense of drilling holes in a printed circuit board and which allow higher density of interconnections.
Hence, a particular transistor may be described as silicon, surface-mount, BJT, n–p–n, low-power, high-frequency switch.
At the other extreme, some surface-mount microwave transistors are as small as grains of sand.
Modern high-power LEDs such as those used for lighting and backlighting are generally found in surface-mount technology (SMT) packages (not shown).
Standard-tolerance surface-mount technology (SMT) resistors are marked with a three-digit code, in which the first two digits are the first two significant digits of the value and the third digit is the power of ten (the number of zeroes).
By the end of the 20th century, surface-mount packages allowed further reduction in the size and weight of systems.
