Overview
The Würth Elektronik 156120RS75300 is a single-color red LED from the WL-SMRW series, designed for surface-mount technology in a 1206 (3216 metric) package. It emits light at a peak wavelength of 632 nm with a typical forward voltage of 2 V at a test current of 20 mA. The component features a round, flat lens with water-clear transparency and offers a viewing angle of 140 degrees. It operates within a temperature range of -40 °C to +85 °C and has a maximum power dissipation of 60 mW.
Feature Summary
- Utilizes a bottom-entry mounting configuration for standard surface-mount assembly processes.
- Features a round, flat lens design with water-clear transparency to optimize light transmission.
- Provides a wide 140-degree viewing angle suitable for general indicator applications.
Applications
- Electronic device status indicators
- Panel-mounted visual signaling
- General-purpose circuit board illumination
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact optical and electrical characteristics. Ensure compatibility with RoHS directives if required by your project specifications. Confirm moisture sensitivity levels and recommended reflow soldering profiles prior to production integration.
Selection Notes
Select this component when a low-profile, standard 1206 footprint is required for red indication. Consider the 2 V forward voltage drop for driver circuit design. The 140-degree viewing angle makes it suitable for applications requiring broad visibility rather than focused beam projection.
Part Context
This part belongs to the WL-SMRW series of single-color LEDs manufactured by Würth Elektronik. The series focuses on compact surface-mount solutions for various color options. The 1206 package size provides a balance between component visibility and PCB space efficiency.
Replacement Considerations
Consult the manufacturer's RedExpert tool or official cross-reference lists for verified substitutes. Ensure any replacement matches the 1206 footprint, 2 V forward voltage, and 632 nm peak wavelength requirements.
