Instructions for Use - Environmental Considerations

Performance may be affected in environments with: liquids (water, oil, chemicals), direct sunlight, dust, sea winds, corrosive gases (Cl2, H2S, Nh3, SO2, No2), static electricity, electromagnetic waves, proximity to heat-producing components or flammable items, sealing or coating with resin/other materials, unclean solder or water-based cleaning agents after soldering.

Instructions for Use - Precautions

1. Avoid applying power exceeding normal rated power. 2. Handle with care when picking up with tweezers to prevent chipping. 3. Soldering tip should not touch the product during manual installation.
