2. SMD LED - Wikipedia

   en.wikipedia.org/wiki/SMD_LED

   The light from white LED lamps and LED strip lights is usually provided by industry standard surface-mounted device LEDs (SMD LEDs). [2] 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 ...

3. 1N4148 signal diode - Wikipedia

   en.wikipedia.org/wiki/1N4148_signal_diode

   The JEDEC registered part numbers 1N914 and 1N4148 were originally only available in an axial package, but over time similar parts became available in surface-mount packages too. Through-hole package. 1N4148 in DO-35 glass axial package. [8] [9] [7] [10] [11] Surface-mount packages. LL4148 in MiniMELF package. [10] [12] [13] 1N4148W in SOD-123 ...

4. Light-emitting diode - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode

   An LED strip, tape, or ribbon light is a flexible circuit board populated by surface-mount light-emitting diodes (SMD LEDs) and other components that usually comes with an adhesive backing. Traditionally, strip lights had been used solely in accent lighting, backlighting, task lighting, and decorative lighting applications, such as cove lighting.

6. Surface-mount technology - Wikipedia

   en.wikipedia.org/wiki/Surface-mount_technology

   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 ).

7. Electronic symbol - Wikipedia

   en.wikipedia.org/wiki/Electronic_symbol

   Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...

8. Dual in-line package - Wikipedia

   en.wikipedia.org/wiki/Dual_in-line_package

   Because some modern chips are available only in surface-mount package types, a number of companies sell various prototyping adapters to allow those surface-mount devices (SMD) to be used like DIP devices with through-hole breadboards and soldered prototyping boards (such as stripboard and perfboard). (SMT can pose quite a problem, at least an ...

9. Troffer - Wikipedia

   en.wikipedia.org/wiki/Troffer

   A troffer is a rectangular light fixture that fits into a modular dropped ceiling grid (i.e. 2' by 2' or 2' by 4'). Troffer fixtures have typically been designed to accommodate standard fluorescent lamps (T12, T8, or T5), but are now often designed with integral LED sources. Troffers are typically recessed sitting above the ceiling grid, but ...
