Mounting and Soldering Profile:

Avoid bending component leads by hand; use proper tools
Ensure terminal pitch matches substrate board's hole pitch
Place component at least 5mm from PCB edge to avoid heat damage during soldering
Pre-heat temperature of 105°C or less before solder wave immersion
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 necessary
Avoid harsh organic solvents
Clean at room temperature and limit washing to one minute
Circuit Design Notes:

Use protective current-limiting resistors for safe 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
