Surface Mount Device (SMD)

maker

A type of electronic component that is mounted directly onto the surface of a printed circuit board (PCB).

expanded

Surface Mount Devices (SMD) are electronic components that are designed to be placed directly on the surface of printed circuit boards (PCBs), as opposed to being inserted through holes. This design allows for more efficient use of space and enables the production of smaller and more complex electronic assemblies, which is critical in modern, compact electronics like smartphones and laptops.

examples

LED with a 0.5 mm height and a 1.6 mm2 footprint, such as the Osram LS E65C.

Used in consumer electronics for creating energy-efficient, space-saving backlighting in displays.

A 0603 resistor measuring 1.6 mm x 0.8 mm, such as the Vishay CRCW06036510F.

Commonly utilized in mobile devices to provide precise resistance within signal processing circuits.
