Mounting and Soldering Recommendations:

Not compatible with reflow soldering for through-hole displays.
Consult Kingbright for compatibility if components will undergo multiple soldering processes or intense heat exposure.
Pre-heat temperature should be 105°C or less before soldering.
Maximum solder bath temperature of 260°C for 3-5 seconds.
Cleaning Instructions:

Use mild "no-clean" fluxes for soldering.
Wash components with water only if cleaning is required, avoiding harsh organic solvents.
Clean at room temperature and do not wash for more than one minute.
Remove excess moisture with forced-air drying immediately after water cleaning.
Circuit Design Notes:

Consider protective current-limiting resistors for operating LEDs within the specified range.
Design the driving circuit to protect against reverse voltages and transient spikes.
Choose the safe operating current based on the maximum ambient temperature.
Precautionary Notes:
