• Designed for bottom-entry surface mount installation

Applications

• General indicator lighting
• Electronic status signaling
• Control panel illumination

Procurement Notes

Verify the specific ordering suffix to confirm the exact color and packaging configuration, as variations exist within the product line. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications before finalizing procurement orders. Cross-reference manufacturer datasheets for accurate handling instructions.

Selection Notes

Select this component when a low-profile 1205 footprint is required for red indication applications. Consider the 160-degree viewing angle provided by the diffused lens design. Ensure circuit design accommodates the 2 V forward voltage drop and 20 mA test current parameters for proper operation.

Part Context

This part belongs to the WL-SMRD series of single-color LEDs manufactured by Würth Elektronik. The series offers various color options in the compact 1205 SMD package, suitable for space-constrained electronic designs requiring reliable visual feedback components.
