Cleaning:

Use mild "no-clean" fluxes for soldering
If cleaning is required, wash components with water only
Avoid harsh organic solvents that may damage plastic parts
Clean at room temperature and limit washing to one minute
Mounting Method:

Do not bend component leads by hand without proper tools
Ensure terminal pitch matches substrate board's hole pitch
Place component at least 5mm from PCB edge to avoid heat damage
Circuit Design Notes:

Consider protective current-limiting resistors for LED operation
Design driving circuit to protect against reverse voltages and spikes
Choose safe operating current based on maximum ambient temperature
Avoid prolonged reverse bias to prevent metal migration
