Chip Resistor Instructions for Use
Application in Special Environments
Product performance may be affected in the following environments:
- Use in various liquids (water, oils, chemicals, organic solvents).
- Outdoor use exposed to direct sunlight or dusty conditions.
- Exposure to sea winds or corrosive gases (Cl2, H2S, Nh3, SO2, No2, etc.).
- Exposure to static electricity or electromagnetic waves.
- Proximity to heat-producing components, plastic cords, or other flammable items.
- Sealing or coating with resin or other coating materials.
- Use involving unclean solder or cleaning with water/water-soluble cleaning agents after soldering.
Precautions on Use
- Avoid applying power exceeding normal rated power, as it may negatively affect product performance and reliability.
- Handle with care when picking up products with tweezers to prevent chipping of the overcoat or body.
- Ensure the soldering tip does not touch the product during manual installation.
