Operation and Storage Instructions
Special Environment Applications: Performance may be affected in environments involving liquids (water, oils, chemicals, organic solvents), direct sunlight, dusty conditions, sea winds, corrosive gases (Cl2, H2S, Nh3, SO2, No2), static electricity, electromagnetic waves, proximity to heat-producing components or flammable items, and sealing/coating with resin or other materials. Cleaning with unclean solder or water/water-soluble cleaning agents after soldering can also impact performance.
Precautions on Use:
- Avoid applying power exceeding normal rated power.
- Handle with care when picking up with tweezers to prevent chipping of the overcoat or body.
- Ensure the soldering tip does not touch the product during manual installation.
