#190148 - That was kind of my point
Responding to: Jan Waclawek's previous message
Jan Waclawek said:
I've never seen a potentiometer specsheet or whatever other material may there be, which would go beyond the power specs and max voltage. They invariantly assume the potentiometer is used as a voltage divider with no load on the wiper.

Yes, that was kind of my point: if they had intended them to be used in applications where it mattered, then they would have specified it.

I certainly wouldn't expect to get any such help for cheap, "commodity" components. If anything, you would need to be looking at specialist (read, "more expensive") parts.

I guess it might be more likely to be included for parts which are specified for higher powers anyhow...?
