Resistance Value Code and Marking Rules
- E-24 Series (0603, 5%): Three-digit marking (significant digits + number of zeros).
- E-24 Series (0603, 1% & 0.5%): Three-digit marking with an underline.
- E-96 Series & E-24 Series (1% & 0.5%) for 0805, 1206, 1210, 2010, 2512, 4R02, 4R03: Four-digit marking (significant digits + number of zeros).
- E-96 Series (0603): Three-code marking (two digits for E-96 resistance code + letter for multiplier code).
- Decimal point denoted by "R".
- Jumper resistors denoted by "0".
- 0201 and 0402 sizes are not marked.
- Non-IEC standard series use markings closest to IEC E24 series nominal values.
- Custom marking available upon agreement.
Chip Resistor Instructions for Use
- Environmental Considerations: Performance may be affected in environments with liquids, direct sunlight, dust, corrosive gases, static electricity, electromagnetic waves, proximity to flammable items, resin sealing, or use of unclean solders/cleaning agents.
- Precautions: Avoid exceeding rated power. Handle with care to prevent chipping. Ensure soldering tip does not touch the product during manual installation.
