1.8AD

Overview

The Bivar Inc. 1.8AD is a single-color through-hole discrete LED with a 1.8mm package size. It emits amber light at a wavelength of 605 nm and features a diffused lens for uniform light output. The component has a luminous intensity of 20 mcd, a forward voltage of 2 V, and a power rating of 10 mW. It offers a 50-degree viewing angle and utilizes a dome-shaped lens profile.

Feature Summary

• Through-hole mounting style with built-in strain relief on the lead frame
• Diffused lens design providing uniform light distribution
• Amber emission color optimized for visibility

Applications

• Right angle holder assemblies requiring lead bends
• Panel indicator applications
• General equipment status indication

Procurement Notes

Verify the specific datasheet version and lifecycle status before procurement, as availability may vary by region. Confirm that the through-hole package dimensions match the target PCB layout. Ensure the forward current requirements align with the circuit design to prevent exceeding the 10 mW power rating. Check for any RoHS compliance documentation if required by the project specifications.

Selection Notes

Select this component when a compact 1.8mm form factor is required for panel mounting. Choose the diffused lens variant over water clear options if uniform illumination is preferred over maximum intensity. Consider the 50-degree viewing angle for applications where broad visibility is necessary. Verify compatibility with right-angle holders due to the shouldered lead frame design.

Part Context

This part belongs to the 1.8mm discrete LED series from Bivar Inc., designed for space-constrained electronic assemblies. The series includes various colors and lens appearances, such as pure green or yellow variants. The 1.8AD specifically addresses needs for amber indicators in industrial and consumer electronics where reliable visual signaling is critical.

Replacement Considerations

Direct substitutes within the same series include other 1.8mm LEDs like the 1.8PGC or 1.8YDL, though these differ in color and electrical characteristics. When replacing, ensure the new component matches the physical package dimensions and lead spacing. Verify that the replacement LED meets the same forward voltage and current requirements to maintain circuit integrity.
