156120M173000

Overview

The 156120M173000 is a surface-mount RGB LED from the WL-SFRW series by Würth Elektronik. It integrates red, green, and blue emitters in a compact 1206 (3216 metric) package with dimensions of 3.2 mm length, 1.6 mm width, and 1.85 mm height. The component features a rectangular lens shape with a wide viewing angle of 120 degrees. Electrical specifications include a forward current of 20 mA for each color channel and a typical forward voltage of 2.4 V. The device operates within a temperature range of -40°C to +85°C and is moisture sensitive.

Feature Summary

• Integrates red, green, and blue light sources into a single surface-mount package
• Provides a wide 120-degree viewing angle for broad visibility
• Designed for narrow space applications due to compact 1206 footprint

Applications

• Status indication in consumer electronics
• Backlighting for compact devices
• Indicator lights in automotive interfaces

Procurement Notes

Verify the specific ordering code against the manufacturer's official documentation to ensure correct binning and lens characteristics. Confirm RoHS compliance status and humidity sensitivity handling requirements prior to assembly. Cross-reference the datasheet for any updates regarding recommended soldering profiles or reflow conditions to maintain component integrity during manufacturing.

Selection Notes

Select this component when a single-package solution for multi-color indication is required in space-constrained designs. The 1206 form factor offers a balance between optical output and board real estate. Ensure the application circuit can support the 20 mA per channel current requirement and that the 2.4 V forward voltage aligns with the system's drive logic levels.

Part Context

This part belongs to the WL-SFRW series of surface-mount LEDs manufactured by Würth Elektronik. The series is characterized by its low profile and high brightness capabilities suitable for modern electronic assemblies. The 156120M173000 specifically utilizes a rectangular lens design to optimize light distribution across the specified viewing angle while maintaining a standard industry-compatible footprint.

Replacement Considerations

Direct substitutes may include other 1206 RGB LEDs from manufacturers such as Everlight or Kingbright, provided they match the 3216 metric package dimensions and electrical parameters. Verify that alternative components offer comparable viewing angles and forward voltage tolerances to ensure consistent performance in the target application.
