Not shown here, are even smaller chip capacitors of 01005 (0402 metric) and 0201 (0603 metric) sizes. Surface-mount capacitor. Surface-mount technology (SMT) is a method for producing electronic circuits in which the components are mounted or placed directly onto the surface of printed circuit boards (PCBs). An electronic device so made is called a surface-mount device (SMD). In the industry it has largely replaced the through-hole technology construction method of fitting components with wire leads into holes in the circuit board.
