LED Indication - Discrete Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact optical and electrical characteristics. Ensure that the procurement channel provides valid traceability documentation. Confirm that the received components match the specified package dimensions and lead-free status. Check for any recent product change notices that may affect availability or specifications.

LED Indication - Discrete Selection Notes

Select this component when a low-profile yellow LED is required for space-constrained designs. The 0.8 mm height allows for thin form-factor devices. Verify that the 20.0 mcd intensity meets visibility requirements for the intended application environment. Ensure compatibility with standard infrared reflow soldering profiles during manufacturing integration.

LED Indication - Discrete Part Context

This part belongs to the Everlight 17-21 series of single-color SMD LEDs. The series is characterized by its small rectangular package size, which is significantly smaller than traditional lead-frame components. This design philosophy prioritizes miniaturization and higher packing density for modern surface-mount assembly processes.
