CSL1901 Series 0603 Low-Current Emission LEDs

ROHM's CSL1901 series 0603 size (0.6" × 0.3") LEDs are optimized for low-light applications such as indicators and numeric displays in factory automation (FA) equipment and communication control equipment.

In recent years, technological advancements in LED elements have dramatically improved luminous efficiency, increasing brightness. At the same time, the market is demanding LEDs tailored to characteristics in the low-current range. This results in higher brightness, making it necessary to design for appropriate luminous intensity and emission wavelengths in applications where interference with adjacent light emitting parts must be considered.
