		<description><![CDATA[SMD devices are, by their very nature, too small to carry conventional semiconductor type numbers. Instead, a somewhat arbitrary coding system has grown up, where the device package carries a simple two- or three-character ID code. Identifying the manufacturers&#8217; type number of an SMD device from the package code can be a difficult task, involving [...]]]></description>
