Observe precautions for handling electrostatic discharge sensitive devices
Mounting and Soldering Recommendations:

Through-hole displays are not compatible with reflow soldering
For multiple soldering processes, consult with Kingbright for compatibility
Use mild "no-clean" fluxes for soldering and water for cleaning to avoid damage to plastic parts
Follow recommended soldering profile and temperature guidelines
Packing & Label Specifications:

Lead forming should be done with proper tools to avoid bending force on the plastic body
Ensure proper terminal pitch and placement on the PCB to prevent damage during assembly and soldering
Circuit Design Notes:

Incorporate protective current-limiting resistors for safe LED operation
Design the driving circuit to protect against reverse voltages and transient spikes
Select safe operating current considering the maximum ambient temperature
Avoid prolonged reverse bias to prevent metal migration and potential short circuits
