Product announcement on 1608-size high brightness single-rank chip LEDs
SML-D15 series

Minimizes brightness variations between individual LEDs SML-D15 Series

Overview

SML-D15 Series

In automotive applications such as car audio and navigation systems, it is common to specify a particular brightness rank in order to suppress brightness variations.
ROHM developed the SML-D15 series using advanced original process technology that enables stable production of single rank products, ensuring minimal brightness variations in end applications.

Features

■Single brightness rank offered

Conventionally, 4 different ranks are provided for each specified brightness level due to inherent limitations in the manufacturing process. However, ROHM has successfully achieved stable brightness through a comprehensive, integrated production system (from the chip manufacturing stage). This makes it possible to supply high brightness single-rank LEDs that reduce brightness variations by 3/4, ensuring consistent, stable performance in a variety of applications.

Product Comparison (B Rank Specification)
■2-3x brighter than conventional products (SML-D12x8W)

Complete redesign and optimization of the LED element have enabled the brightness to be increased by up to 3 times compared with conventional LEDs, delivering industry-leading brightness in the 1608 size (1.6x0.8mm).

【Brightness Range IF=20mA】
