- Notes
- ^ For illustration only. IEC 60062:2016 and IEC 60757:1982 do not specify or intend to specify color boundaries and properties, and colors shown here as example are applied for the purpose of consistent illustration only.
- ^ 2.0 2.1 Before yellow and grey colored rings were assigned to tolerance values of ±0.02% and ±0.01% with IEC 60062:2016, some manufacturers used yellow and grey as substitute for gold (±5%) and silver (±10%) colored rings in high-voltage resistors to avoid metal particles in the lacquer.
- ^ 3.0 3.1 Any temperature coefficient not assigned its own letter shall be marked "Z", and the coefficient found in other documentation.
- ^ Before a grey colored ring was assigned to a tolerance of ±0.01% with IEC 60062:2016, some manufacturers used a grey colored ring to indicate a non-standardized tolerance of ±0.05%.
