Some resistors from PF2470 series that we sell might have gray color vs standard black color in the same tube from the same batch
As per the manufacturer:
The variation in tone (gray) is the result of minor rework, which may be needed if a marking is unclear. In these cases, the parts are lightly sanded and re-marked, which can cause the surface appearance to look slightly different.
Please note that all parts are re-tested, including Hi-Pot and Electrical Tests, to confirm they fully meet the required specifications and performance standards.
