CSL1104WB White LED

ROHM's CSL1104WB series achieves a high luminous intensity of 2.0 cd in an ultra-compact 1608 size (1.6 mm x 0.8 mm = 1.28 mm²), which was previously difficult to achieve. The result is the same luminosity as the current mainstream 3528 size PLCC package (3.5 mm x 2.8 mm = 9.8 mm²) but in an 87% smaller form factor.

Moreover, color variation (an issue with white LEDs) is significantly improved, simplifying the color adjustment process by ensuring accurate white color chromaticity. This not only contributes to greater application space savings, but also improves design flexibility along with visibility through high-density mounting of high-luminosity LEDs, reducing development load considerably. In addition, qualification under the automotive reliability standard AEC-Q102 specifically developed for optical devices is planned, enabling a smooth application inside industrial equipment and automotive applications exposed to harsh environments.
