SMS1105UWDN

LED Indication - Discrete Overview

The SMS1105UWDN is a surface-mount warm white LED manufactured by Bivar Inc. It utilizes a PLCC-2 package with J-leads for right-angle mounting. The component features a diffused lens and emits warm white light with an intensity of 1750 mcd at a viewing angle of 120 degrees. Electrical characteristics include a forward voltage of 3.2 V and a forward current rating of 20 mA, resulting in a power rating of 100 mW. Physical dimensions are approximately 2.80 mm in length, 1.20 mm in width, and 0.80 mm in height. It operates within a temperature range of -30°C to +80°C.

LED Indication - Discrete Feature Summary

• Right-angle surface mount configuration using PLCC-2 package
• Diffused lens design providing a wide 120-degree viewing angle
• Warm white color output with high luminous intensity
• RoHS compliant construction suitable for automated assembly

LED Indication - Discrete Applications

• Status indication on electronic circuit boards
• Panel indicator lights for consumer devices
• General illumination in compact electronics
• Visual signaling in industrial control equipment

LED Indication - Discrete Procurement Notes

Verify the specific suffix 'UWDN' against official Bivar documentation to confirm exact binning or optical specifications, as distributors may list similar variants like 'UWDW'. Ensure compatibility with RoHS3 standards and check moisture sensitivity level (MSL 4) requirements for storage and handling during procurement.

LED Indication - Discrete Selection Notes

Select this component when a right-angle LED is required for space-constrained PCB layouts. The PLCC-2 package facilitates standard SMT processes. Consider the 120-degree viewing angle and warm white color temperature for applications requiring broad visibility without harsh glare. Verify thermal management needs given the 100 mW power rating.

LED Indication - Discrete Part Context

This part belongs to the Bivar SMS series of low-power surface-mount LEDs. The series offers various colors and lens types in a standardized PLCC-2 footprint. The UWDN variant specifically denotes warm white emission with a diffused lens, distinguishing it from clear lens or different color options within the same mechanical family.

LED Indication - Discrete Replacement Considerations

Direct substitutes may include other PLCC-2 warm white LEDs from manufacturers such as Kingbright or Everlight. Ensure replacement parts match the 2.80mm x 1.20mm x 0.80mm dimensions and 3.2V forward voltage to maintain electrical and mechanical compatibility.
