Resistance Value Code and Marking Rules
All resistance value codes for thick film chip resistors correspond to their markings.
- 0402: No mark on the glass side.
- 0603 and above: Marking rules apply.
Instructions for Use
Environmental Considerations: Performance may be affected in the following environments:
- Exposure to liquids (water, oils, chemicals, organic solvents).
- Outdoor use with direct sunlight or in 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 materials.
- Use of unclean solder or water-based cleaning agents after soldering.
Precautions:
- Avoid applying power exceeding the normal rated power, as it may negatively affect performance and reliability.
- 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.
