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.
