Description for Resistance Value Code and Marking of Thick Film Chip Resistor
Resistance Value Code
All the resistance value code of thick film chip resistor is corresponding with the marking.
Marking
- 0402: No mark on the glass side.
- 0603 and above: Marking rules apply.
Chip Resistor Instructions for Use
Application in Special Environments (may affect performance):
- Use in liquids (water, oils, chemicals, organic solvents).
- Outdoor use exposed to direct sunlight or dusty places.
- 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 of unclean solder or water/water-soluble cleaning agents after soldering.
Precautions on Use:
- Avoid applying power exceeding normal rated power. Exceeding the power rating under steady-state loading may negatively affect product 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.
