The reference book contains code marking (SMD codes) for more than 33 thousand active electronic components (diodes, thyristors, bipolar and field-effect transistors, integrated circuits). SMD codes are divided into types of cases and are arranged in tables in alphanumeric order. Also given are logos and addresses of manufacturers of electronic components, schematic drawings of housings and pin assignments (base) for discrete semiconductor components and most integrated circuits, typical connection schemes for most integrated circuits.
