Overview
The B1811NG--05D001013U1930 is a green surface-mount LED from Harvatek Corporation, designed for discrete indication applications. It features a 0402 (1005 Metric) package with dimensions of 1.00mm length by 0.50mm width and a maximum height of 0.70mm. The component emits light at a peak wavelength of 521nm and a dominant wavelength of 529nm. Typical forward voltage is 2.8V at a test current of 20mA. It offers a viewing angle of 125 degrees and a luminous intensity of 285mcd. The lens is diffused with a rectangular flat-top style.
Feature Summary
- Compact 0402 form factor suitable for space-constrained PCB layouts
- Diffused lens design provides uniform light distribution
- High brightness output in the green spectrum
Applications
- Status indicators on electronic devices
- Backlighting for keypads and displays
- Direct-view panel illumination
Procurement Notes
Verify the specific suffix codes against the manufacturer datasheet to ensure correct lens type and wavelength specifications. Confirm RoHS compliance and MSL rating prior to assembly. Check for alternate part numbers that may differ only in packaging or minor electrical tolerances. Ensure storage conditions meet humidity sensitivity requirements before reflow soldering.
Selection Notes
Select this component when a small footprint is required alongside high visibility green indication. Compare forward voltage and luminous intensity against system power constraints. Consider the diffused lens property if glare reduction is necessary compared to clear lens alternatives. Verify compatibility with standard SMT reflow profiles for the 0402 package size.
Part Context
This part belongs to the B1811 Series of SMD LEDs from Harvatek Corporation. The series includes various colors and package sizes, ranging from ultra-compact 0402 to larger top-view packages. These components are generally used for status indication and backlighting in consumer electronics and industrial equipment where space efficiency is critical.
Replacement Considerations
Check for exact matches in package size, pin configuration, and electrical parameters. Verify that any substitute maintains the same viewing angle and luminous intensity requirements. Ensure the replacement part supports the same mounting technology and thermal characteristics.
