ALMD-LB38-TV002

Overview

The ALMD-LB38-TV002 is a single-color blue LED indicator from Broadcom Limited, designed for surface-mount technology (SMD/SMT) applications. It features an oval dome lens with diffused transparency and measures 4.20 mm in length and width, with a maximum height of 7.00 mm. The component operates at a peak wavelength of 464 nm and a dominant wavelength of 470 nm. Electrical characteristics include a typical forward voltage of 3.2 V and a rated power of 70 mW when driven at a test current of 20 mA. Optical performance specifies a light intensity of 1090 mcd with viewing angles of 40° and 100°. It is housed in a 4-SMD gull-wing package.

Feature Summary

• Utilizes InGaN technology to produce high-intensity blue light output
• Features a diffused oval dome lens for wide-angle visibility
• Designed for reliable surface-mount assembly on printed circuit boards

Applications

• General purpose electronic status indication
• Panel indicators for industrial equipment
• Consumer appliance control interfaces

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required optical and electrical parameters. Confirm moisture sensitivity level (MSL 2A) handling requirements during storage and reflow soldering processes. Check RoHS compliance status against project specifications. Ensure the gull-wing package dimensions align with the designated footprint on the PCB layout to prevent assembly defects.

Selection Notes

Select this component for applications requiring a standard blue indicator with moderate viewing angles. Consider the 3.2 V forward voltage drop when designing drive circuits. Evaluate the 1090 mcd intensity against ambient lighting conditions. Compare physical dimensions against available board space. Assess thermal management needs based on the 70 mW power rating and operating temperature range.

Part Context

This part belongs to the ALMD-LB38 series of single-color LEDs manufactured by Broadcom Limited. The series offers various lens colors and viewing angles to suit different visual indication needs. The ALMD-LB38-TV002 specifically provides a blue diffused lens configuration optimized for general signaling tasks in compact electronic assemblies.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure replacement parts match the 4-SMD gull-wing package and 4.20 x 4.20 mm dimensions. Verify identical electrical parameters including forward voltage and test current. Confirm compatible peak wavelength and optical intensity for visual consistency.
