Soldering Profile and General Notes
Through-hole displays are incompatible with reflow soldering.
Mild "no-clean" fluxes are recommended for soldering.
Cleaning should be done with water only, avoiding harsh organic solvents.
Circuit Design Notes
Use protective current-limiting resistors for LED operation within the specified range.
Design the driving circuit to protect against reverse voltages and transient spikes.
Choose the safe operating current considering the maximum ambient temperature.
Precautionary Notes
Refer to the latest datasheet for updated specifications before production usage.
Operate the product within the environmental and electrical limits specified in the datasheet.
For special processes such as potting for LED assembly, consult with Kingbright representative.
