Introduction
Surface mount devices(SMDs) are used in a growing number of commercial and industrial products. SMDs
have improved performance over through-hole components due to their smaller size, shorter internal leads, and
smaller board layouts. These factors reduce the circuit’s parasitic inductance and capacitance. SMDs can also be
more cost effective than traditional through-hole components due to the smaller board size, fewerboard layers,
and fewer holes. Today more than 50% of active semiconductor components are surface-mounted.
At the same time, SMD devices are, by their very nature, too small to carry conventional semiconductor type
numbers. Therefore, a somewhat arbitrary coding system has grown up, where the device package carries a simple
one, two or more character or graphic SMD code. Thus it is necessaryto take into account that the colour and (or)
placing of alphanumeric or graphic symbols are also important.
Identifying the manufacturers type number of an SMD device from the package code can be a difficult task.
Unfortunately, each device code is not necessarily unique.
It is possible for various manufacturers to place different devices in the same case with the same SMD-code.
