L199LWD-35K-TR

LED Indication - Discrete Overview

The L199LWD-35K-TR is a warm white surface-mount LED from American Opto Plus LED, designed for indicator applications. It features a compact 0402 (1005 metric) package with dimensions of 1.0mm length by 0.5mm width and height. The component emits light at a color temperature of 3500K with a typical forward voltage of 3.1V at a test current of 20mA. It offers a luminous intensity of 310mcd and a wide viewing angle of 150 degrees, housed in a yellow lens.

LED Indication - Discrete Feature Summary

• Compact 0402 SMD form factor suitable for space-constrained PCB layouts
• Wide 150-degree viewing angle for broad illumination visibility
• Warm white emission profile optimized for ambient lighting indicators

LED Indication - Discrete Applications

• Status indication on consumer electronics devices
• Backlighting for small display interfaces
• Indicator lights in automotive interior panels
• Signal indication in industrial control equipment

LED Indication - Discrete Procurement Notes

Verify the specific suffix 'TR' confirms tape-and-reel packaging when ordering. Confirm the 3500K color temperature variant matches design requirements against other available Kelvin options. Ensure compatibility with standard reflow soldering profiles for 0402 packages. Cross-reference the manufacturer's latest datasheet for any updates to mechanical outline or electrical ratings prior to finalizing procurement specifications.

LED Indication - Discrete Selection Notes

Select this component when a low-profile warm white indicator is required for high-density boards. The 150-degree viewing angle provides superior visibility compared to narrow-beam alternatives. Consider the 3.1V forward voltage drop for power supply calculations. Evaluate the 310mcd output against ambient light conditions to ensure adequate visibility without excessive current draw.

LED Indication - Discrete Part Context

This part belongs to the L199LWD series of ultra-thin SMD LEDs manufactured by American Opto Plus LED. The series focuses on miniaturized components for modern electronic assemblies. The 0402 footprint allows for automated placement in high-volume manufacturing environments. The product line emphasizes reliability and consistent optical performance across various environmental conditions.

LED Indication - Discrete Replacement Considerations

Direct substitutes include the L199LWD-56K-TR for cool white variants within the same package family. Verify pinout compatibility and thermal characteristics before swapping. Check if alternative manufacturers offer identical 0402 warm white LEDs with matching 3.1V Vf and 310mcd intensity.
