The differences between surface-mounted components and surface-mounted devices are as follows:
1. Surface-mounted components are all sheet structures. Surface mounting components refer to electronic components that are rectangular, cylindrical or special-shaped in shape, without leads or short leads, and whose soldering ends or pins are made in the same plane and are suitable for surface mounting. It is a miniature electronic component with no leads or very short leads, suitable for surface mounting.
2. The surface-mounted device is small in size and can be directly attached to the PCB for soldering without the need for through holes, which can greatly improve the PCB integration. Type: PLCC plastic-encapsulated chip carrier with pins.
