The codes given in the chart below usually tell the length and width of the components in tenths of millimeters or hundredths of inches. For example, a metric 2520 component is 2.5 mm by 2.0 mm which corresponds roughly to 0.10 inches by 0.08 inches (hence, imperial size is 1008).
Surface-mount technology (SMT), originally called planar mounting, [1] is a method in which the electrical components are mounted directly onto the surface of a printed circuit board (PCB). [2] An electrical component mounted in this manner is referred to as a surface-mount device ( SMD ).
Non-SMD types of LED lighting also exist, such as COB (chip on board) and MCOB (multi-COB). Surface-mounted device LED modules are described by the dimensions of the LED package. A single multicolor module may have three individual LEDs within that package, one each of red, green and blue, to allow many colors or shades of white to be selected ...
M7 general purpose diode in DO-214AC (SMA) package (surface mount version of 1N4007) [1] DO-214 is a standard that specifies a group of semiconductor packages for surface-mounted diodes . Overview
SOD-123 package. Small Outline Diode (SOD) is a designation for a group of semiconductor packages for surface mounted diodes.The standard includes multiple variants such as SOD-123, SOD-323, SOD-523 and SOD-923. [1]
The Thin shrink small outline package has a smaller body and smaller lead pitch than the standard SOIC package. It is also smaller and thinner than a TSOP with the same lead count.
A thin-shrink small-outline package (TSSOP) is a rectangular, thin-body component. A TSSOP's leg count can range from 8 to 64. A TSSOP's leg count can range from 8 to 64. TSSOPs are particularly suited for gate drivers, controllers, wireless / RF , op-amps , logic , analog , ASICs , memory ( EPROM , E2PROM ), comparators and optoelectronics .
Flatpack is a US military standardized printed-circuit-board surface-mount-component package. The military standard MIL-STD-1835C defines: Flat package (FP). A rectangular or square package with leads parallel to base plane attached on two opposing sides of the package periphery.
