With their high brightness and small size, the PCB-based devices released today are the perfect choice for small scale products that are expected to work reliably in arduous environments. The LEDs provide designers with increased design-in flexibility and high performance in backlight keypads and displays for navigation systems, cell phones, industrial control systems, and traffic signals and message boards.

The VLMTG1400 series features luminous intensity from 1,200 mcd to 2,800 mcd at 20 mA, a typical wavelength of 525 nm, and forward voltage from 2.75 V to 3.2 V. The devices are grouped by luminous intensity, wavelength, and forward voltage, and they offer an extremely wide viewing angle of 146°.
