Ultra compact 0603 Size, High Intensity Reflector Type White LED
The CSL1104WB is a white LED that achieves a high luminous intensity of 2.0 cd in an ultra-compact 0603 size. This ultra-compact product contributes to space saving of applications. Since high-density mounting is possible, it also contributes to improving design, such as enabling blackout expression of panels. Color variation is the issue for white LEDs, but this product has improved this and subdivided the chromaticity rank system. This simplifies the color adjustment process and reduces application development effort.
We have a lineup of series products with different chromaticities.
The CSL1104WB series achieves a high luminous intensity of 2.0cd in an ultra-compact 1608 size (1.6mm x 0.8mm = 1.28mm2), which was previously difficult to achieve. The result is the same luminosity as the current mainstream 3528 size PLCC package (3.5mm x 2.8mm = 9.8mm2) 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.
1．High brightness in an ultra-compact size improves design flexibility
The new CSL1104WB series of reflector-type white LEDs provide high 2.0cd luminous intensity in a compact 1608 size by leveraging proprietary compact package technology and adopting a high luminosity chip. As a result, the same luminous intensity as the standard 3528 size PLCC package (3.5mm x 2.8mm = 9.8mm2) is achieved but in the 1608 size, reducing mounting area by 87%. This doesn’t only contribute to greater application space savings, but also improves flexibility of design along with visibility (e.g. complete blackout on panels) by supporting high density mounting of high luminous intensity LEDs, reducing development load considerably.
At the same time, compliance with the automotive reliability standard AEC-Q102 specifically formulated for optical devices is planned, ensuring a smooth application inside industrial equipment and automotive applications exposed to harsh environments.
2．Fine-grained, accurate white color chromaticity simplifies color adjustment
This new product improves color variability, which is an issue with white LEDs, enabling accurate, detailed white representation. Achieving color uniformity simplifies the process of color adjustment, significantly reducing the amount of man-hours required for application development (i.e. faithfully reproducing brand colors).
