HSMS-C177

LED Indication - Discrete Overview

The HSMS-C177 is a single-color red LED from Broadcom Limited, manufactured in the 0805 (2012 metric) surface-mount package. It features a diffused lens with dimensions of 2.00 mm length by 1.25 mm width and a maximum height of 0.80 mm. The device emits light at a peak wavelength of 630 nm, with a typical forward voltage of 2.1 V at a test current of 20 mA. Optical performance includes a viewing angle of 170 degrees and a luminous intensity of 10 mcd.

LED Indication - Discrete Feature Summary

• Utilizes a diffused optical element to provide wide-angle illumination suitable for indicator applications.
• Designed for compatibility with standard infrared soldering processes during assembly.
• Constructed with a rectangular lens featuring a flat top profile for consistent visual appearance.

LED Indication - Discrete Applications

• General purpose status indicators on electronic equipment panels
• Front panel illumination for control interfaces
• Button backlighting in consumer devices

LED Indication - Discrete Procurement Notes

Verify component authenticity through authorized distribution channels due to potential availability of non-genuine parts. Confirm RoHS compliance status and moisture sensitivity level (MSL 2A) requirements prior to PCB assembly planning. Ensure storage conditions adhere to humidity control standards to prevent package degradation before reflow soldering.

LED Indication - Discrete Selection Notes

Select this component when a low-profile red indicator is required within standard 0805 footprint constraints. Consider the 170-degree viewing angle for visibility needs and verify that the 2.1 V forward voltage aligns with the driving circuit design. Evaluate thermal management capabilities against the specified power rating for long-term reliability.
