Resistance Value Code and Marking Rules

Resistance Value Code

All the resistance value codes of thick film chip resistors correspond with their markings.

Marking
  • E-24 Series (0603, 5%): Three digits. First two are significant figures, third is the power of 10.
  • E-24 Series (0603, 1% & 0.5%): Three digits with an underscore below.
  • E-96 Series & E-24 Series (1% & 0.5%) for 0805, 1206, 1210, 2010, 2512, 4R02, 4R03: Four digits. First three are significant figures, fourth is the power of 10.
  • E-96 Series for 0603: Three codes. First two digits are E-96 resistance code, third is a letter for multiplier code.
  • Decimal point is represented by R.
  • Jumper resistors are represented by 0.
  • 0201, 0402: No marking on the glass side.
  • For non-IEC standard series, marking follows the closest IEC E24 series nominal resistance.
  • Special marking requirements are printed as per agreement.

Chip Resistor Instructions for Use

Application in Special Environments

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 coating materials.
  • Use of unclean solder or cleaning with water/water-soluble agents after soldering.
Precautions on Use
  • Avoid applying power exceeding normal rated power, as it may negatively affect performance and reliability.
  • Handle with care when picking up with tweezers to avoid chipping the protective coating or resistor body.
  • Ensure the soldering tip does not touch the product during manual installation.
