Usage & Handling Precautions

• Environmental Considerations: Performance may be affected by use in liquids (water, oil, chemicals, organic solvents), direct sunlight, dusty environments, sea winds, corrosive gases (Cl2, H2S, Nh3, SO2, No2), static electricity, electromagnetic waves, proximity to heat-producing components or flammable items, sealing with resin/coating materials, or using unclean solder/cleaning agents after soldering.
• Handling Precautions: Avoid exceeding normal rated power. Handle with care when picking up with tweezers to prevent chipping. Ensure soldering tip does not touch the product during manual installation.
