ROHM Introduces New White Chip LEDs

ROHM Semiconductor introduced their new CSL1104WB ultra-compact, high luminous intensity white chip LEDs.

The products are optimized for applications requiring high brightness white light emission, such as IoT devices, drones, and other battery-equipped applications.

In recent years, high luminous intensity (2.0cd) white LEDs have been increasingly adopted to improve visibility in a range of applications in the consumer electronics and automotive sectors. At the same time, the emergence of applications that mount multiple LEDs in a small space – such as IoT devices and drones – require high density mounting. This makes it difficult to achieve high brightness in a compact footprint.

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.
