LEDs offer non-standard colours

Keywords:LED  wavelength customisation  phosphor technology 

ROHM Semiconductor reveals LEDs based on advanced phosphor technology that allow wavelength customisation to obtain colours such as pink, blue green, blue lagoon, sapphire blue, ice blue and incandescent bulb in addition to the eight standard colours: dark red, red, orange, yellow, yellow-green, green, blue and white. The LEDs offer a broad range of applications that include automotive, consumer, gaming, industrial and more.

For greater compatibility, designers can choose from various package types—from an ultra-thin packaging of 1.6 x 0.8 x 0.36mm (0603) up to 3 x 2 x 1.3mm (1206). The overall chip LED line-up consists of standard type, top-view type, side-view and reverse-mount types that provide maximum design and soldering flexibility.

The LEDs feature power dissipation of 54mW, forward current of 20mA, peak forward current of 100mA/kHz, reverse voltage of 5V and forward voltage 2.2V at 10mA. They also offer luminous intensity of 100mcd at 20mA, operate at a temperature range of 40°C to 85/100°C and can be stored at -40°C to 100°C. The products are available on a made-to-order basis.
