Chip Resistor Instructions for Use
Application in Special Environments
Product performance may be affected in the following environments:
- Use in various liquids (water, oil, 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 flammable items.
- Sealing or coating with resin or other coating materials.
- Use of unclean solder or water/water-soluble cleaning agents after soldering.
Precautions on Use
- Avoid applying power exceeding normal rated power, as this may negatively affect performance and reliability.
- Handle with care when picking up with tweezers to avoid chipping the overcoat or body.
- Ensure the soldering tip does not touch the product during manual installation.
