It is a Yellow Surface Mount LED. An LED is a two-lead semiconductor light source, which emits lights when activated. When an appropriate voltage is applied to the LED terminal the electrons recombine with the electron holes within the device and release energy in the form of photons, this effect is known as electroluminescence. The energy bandgap between the semiconductor determines the color of the LED
There are more and more hobbyists taking advantage of surface mount technology these days. With affordable tools like hot air and hotplate reflow ovens, electronics enthusiasts are shrinking their projects down to new levels of portability. Unfortunately, It’s not always easy to get your hands on small amounts of SMD parts so here’s a part that every project could use more of tiny little LEDs.
- Low power consumption
- Wide viewing angle
- Ideal for backlight and indicator
