Active325,386 in stock

Overview

The SML-D12U1WT86 is a high-brightness red surface-mount LED from Rohm Semiconductor, housed in a standard 0603 (1608 metric) package. It features a transparent resin lens and a peak wavelength of 620nm, providing clear visual indication for low-power electronic assemblies. Designed for high reliability, this LED operates at a standard test current of 20mA.

Why Choose This Part

The component offers a low profile height of 0.65mm, making it suitable for height-constrained enclosures and thin wearable devices. Its 0603 footprint is a standard industry size that balances ease of automated pick-and-place assembly with high board-density requirements. With an operating temperature range of -40C to 85C, it maintains stable performance across diverse industrial and consumer environments.

Applications

Status Indicators
Visual feedback for power rails, error states, or connectivity status in embedded systems.
Control Panel Backlighting
Providing localized illumination behind buttons or legends in compact consumer interfaces.
Diagnostic Signaling
Board-mounted red LED used to indicate fault conditions during firmware debugging or field service.

Getting Started

Integration requires a current-limiting resistor calculated based on the 2.2V typical forward voltage and the desired brightness level at 20mA. Ensure correct polarity orientation during assembly by matching the cathode mark on the 1.6mm x 0.8mm package with the PCB footprint. Standard reflow soldering profiles for SMD components apply.
