LED Indication - Discrete Procurement Notes

Verify the current lifecycle status before procurement, as documentation indicates this part may be obsolete or subject to discontinuation by the manufacturer. Confirm moisture sensitivity handling requirements during storage and reflow soldering processes. Ensure compatibility with standard SMD/SMT assembly equipment and verify that the specified operating temperature range meets the final application's environmental constraints.

LED Indication - Discrete Selection Notes

Select this component when a specific cool white color temperature of 5500 K is required alongside a defined luminous intensity of 650 mcd. The PLCC-2 form factor suits designs needing a low-profile solution with a 120-degree emission pattern. Consider the 3.7 V forward voltage drop for circuit design calculations and ensure the thermal management strategy supports the 127 mW power dissipation within the -40°C to +100°C operational window.
