Two-Color Chip LED

Two-Color Chip LEDThe SML-D22MUW two-color chip LED from Rohm Co. Ltd. is a small-class device with a design that improves reliability along with a backside electrode configuration that supports high-resolution displays.

Board space is reduced by 35 percent over standard 1.5 × 1.3-mm two-color LEDs, contributing to thinner displays. And after taking into consideration usage conditions during reflow, countermeasures were adopted that prevents solder penetration within the resin package to ensure greater reliability.

A compact size contributes to smaller, thinner devices. In addition to element miniaturization, the SML-D22MUW leverages PicoLED mounting and wire bonding technologies to mount two chips. The extremely close configuration of color elements results in excellent color mixing properties that make it possible to produce not only red and green colors, but a number of intermediate colors as well.
