ALMZ-LG37-WX002

LED Indication - Discrete Overview

The ALMZ-LG37-WX002 is a single-color LED indicator manufactured by Broadcom Limited. It utilizes AlInGaP material to emit white light with a peak wavelength of 626 nm, although the model designation indicates white output. The component features an oval lens shape with dimensions of 4.2 mm x 4.2 mm and a viewing angle of 40° x 100°. It operates with a forward current of 20 mA and a forward voltage of 2.1 V, resulting in a power rating of 120 mW. The optical intensity is rated at 2.9 cd. The device is designed for surface mount technology (SMT) installation in a 1717 package.

LED Indication - Discrete Procurement Notes

Verify the specific binning requirements for color and intensity uniformity prior to procurement. Confirm that the supplier provides documentation matching the JEDEC MSL 2A classification. Ensure the received components are compatible with the specified industrial reflow soldering profiles. Check for any specific handling instructions related to the advanced optical grade epoxy used in the lens construction.

LED Indication - Discrete Selection Notes

Select this component when high luminous intensity comparable to through-hole LEDs is required in a surface mount form factor. Consider the wide viewing angle for applications requiring broad visibility. Evaluate the compatibility with existing SMT assembly lines and reflow processes. Assess the suitability of the oval lens shape and tinted/diffused characteristics for the specific signage or display application requirements.

LED Indication - Discrete Part Context

This part belongs to the Avago ALMD-Lx37 Oval LED series, which includes variants in Red, Amber, Green, and Blue colors. The series is engineered to replace conventional high-brightness through-hole LEDs while enabling surface mount assembly.
