Overview
The Würth Elektronik 156120YS82500 is a single-color yellow LED from the WL-SMRW series, designed for surface-mount technology in a 1206 (3216 metric) package. It features a dome-shaped lens with a diameter of 2.3 mm and a height of 1.85 mm. The component emits light at a peak wavelength of 591 nm with an optical intensity of 1.4 cd. Electrical characteristics include a forward voltage of 2 V at a forward current of 20 mA, resulting in a power rating of 48 mW. It operates within a temperature range of -40 °C to +85 °C.
Feature Summary
- Features a water-clear dome lens for focused light emission
- Designed for standard surface-mount reflow soldering processes
- Constructed with a colorless lens material for high transparency
Applications
- General indicator lighting on electronic circuit boards
- Status indication in consumer electronics devices
- Panel status indicators in industrial control equipment
Procurement Notes
Verify the specific part number against official Wurth Elektronik documentation to confirm the exact optical and electrical specifications. Ensure that the ordering suffix matches the required packaging format, such as cut tape or reel, as these affect handling procedures. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement decisions.
Selection Notes
Select this component when a compact 1206 footprint is required alongside high luminous intensity for visibility. The 20 mA drive current and 2 V forward voltage are compatible with standard logic-level drivers. Consider the 20-degree viewing angle for applications requiring directional light output rather than wide-area illumination.
Part Context
This component belongs to the WL-SMRW series of surface-mount LEDs manufactured by Würth Elektronik. The series offers various colors and lens shapes within standardized packages. The 1206 form factor provides a balance between board space efficiency and thermal performance for general-purpose signaling applications.
Replacement Considerations
Consult official Wurth Elektronik cross-reference lists for verified substitutes. Generic replacements may differ in lens geometry, viewing angle, or binning tolerances. Verify mechanical compatibility and spectral consistency before substituting.
