HSMG-C191 LED Application Guide

flux

I’ll research the HSMG-C191 manufacturer specifications, practical LED drive circuits, and sourcing alternatives, then save a cited application guide in the project files.

The source listings conflict with this project’s description: they identify a yellow-green LED rather than a 527 nm device. Datasheet verification is still pending, so I’ll clearly flag unresolved specifications and avoid presenting replacement parts as verified drop-ins.

HSMG-C191 Application and Usage Guide
Broadcom’s HSMG-C191 is a low-profile, two-terminal, surface-mount ChipLED in the 0603 package family (manufacturer product page). Its usual circuit role is a current-limited status indicator or compact backlight; the green color and optical specifications below remain provisional until datasheet verification completes.
Verification status — research draft, not a release-approved specification. The manufacturer datasheet endpoint did not return an accessible PDF, and verification of two mirrored copies is still pending. Numerical datasheet claims are therefore explicitly marked unverified; links identify the source to check, not compl...

I saved the HSMG-C191 Application and Usage Guide in the project files, covering all seven requested sections and source links. It remains a research draft: datasheet verification could not complete, so unresolved ratings and replacement compatibility are explicitly flagged. Distributor listings also conflict with the project’s 527 nm / 3.4 V description; resolving that discrepancy and verifying the datasheet are the next priorities.
