Overview
The 156125M173000 is a full-color RGB LED from the WL-SFRW series, featuring a reverse-mount SMD package in a 1205 (3216 metric) footprint. It integrates red, green, and blue chips within a single water-clear lens to enable multi-color output. The component operates with a forward voltage of 2.4V and supports a maximum power dissipation of 48mW. It offers a wide viewing angle of 120 degrees and is designed for surface mount technology applications requiring compact form factors.
Feature Summary
- Integrates red, green, and blue LEDs for full-color generation
- Features a reverse-mount design suitable for narrow spaces
- Utilizes a water-clear lens for optimal light transmission
- Provides a wide 120-degree viewing angle
Applications
- Status indication in consumer electronics
- Backlighting for compact devices
- Indicator lights in automotive interfaces
- Decorative lighting in IoT modules
Procurement Notes
Verify the specific datasheet version when sourcing, as Würth Elektronik may update mechanical drawings or electrical characteristics over time. Confirm that the reverse-mount orientation aligns with your PCB silkscreen and pad layout. Ensure thermal management strategies account for the 48mW power dissipation limit during continuous operation to maintain reliability and color stability.
Selection Notes
Select this component when space constraints preclude standard top-mount LEDs. The reverse-mount configuration allows for lower profile designs compared to traditional packages. Consider the 1205 footprint dimensions against available board real estate. Evaluate the combined current requirements of the RGB channels to ensure the driving circuitry can handle the total load without exceeding thermal limits.
Part Context
This part belongs to the WL-SFRW series, which specializes in full-color RGB solutions. The series emphasizes compactness and versatility for modern electronic designs. The 156125M173000 specifically addresses the need for high-brightness, multi-color indicators in tight spaces, offering a reliable alternative to discrete LED assemblies.
Replacement Considerations
No public confirmed substitute part numbers are documented for this specific model. Direct replacement requires matching the reverse-mount form factor, 1205 footprint, and RGB spectral characteristics. Consult manufacturer cross-reference guides for potential alternatives if supply chain issues arise.
