Usage Instructions & Precautions
- Environmental Considerations: Performance may be affected in environments with liquids (water, oil, chemicals), direct sunlight, dust, corrosive gases (Cl2, H2S, Nh3, SO2, No2), static electricity, electromagnetic waves, proximity to flammable items, or when sealed with resin/coatings. Cleaning with water or water-soluble agents after soldering is not recommended.
- Power Handling: Avoid applying power exceeding the normal rated power, as it may negatively impact performance and reliability.
- Handling: Use caution when picking up products with tweezers to avoid chipping the protective coating or resistor body.
- Manual Installation: Ensure the soldering tip does not touch the product during manual installation.
