Rohm announces low-light low-current LED


Contributes to improved visibility by reducing uneven brightness and colour in indicators and numeric displays

Rohm has announced the availability of 0603-size (0.6inch × 0.3inch) / 1608-size (1.6 mm × 0.8 mm) LEDs optimised for low-light applications for use in indicators and numeric displays.

The CSL1901 series reduces visual variations in brightness and colour under low-light conditions by optimising element characteristics of light emission at 2mA using original device technology. The LEDs are designed for factory automation equipment (i.e. PLCs) and communication control equipment such as modems and router

In general, when operating standard LEDs, which guaranteed specification at 20mA, at low currents results in brightness and colour differences that vary from part to part. Compared to existing products (at 2mA), Rohm says its new LEDs reduce brightness variations by half and colour sifting by 3nm, minimising design man-hours required for light emission while improving visibility in indicators and numeric displays.

A lineup of five colours is offered in the 0603 size – facilitating replacement due to application and model changes.
