Resistor tolerance has 1% given in the datasheet. Does it include all (ageing, temperature co-efficient, solder joint and manufacturer tolerance.)

For my worst case can I consider 1% alone? Does it include all the error influences of the resistor?

    What does the datasheet say? Usually they are pretty specific about the test conditions for each specification (though you may not have access to the standard). – Spehro Pefhany Mar 25 '22 at 04:45

    [The Photon](https://electronics.stackexchange.com/a/488469/38098) has some comments on this. Worth a read. – jonk Mar 25 '22 at 05:49

    If you read the datahset carefully, you'll probably find it described as 'initial tolerance'. You have to add ageing and tempco on top of that. Link to the datasheet. – Neil_UK Mar 25 '22 at 06:11
  • Normally just manufacturing, temperature comes on top of that. – winny Mar 25 '22 at 09:31
  • Read the complete datasheet very carefully. Look for application notes from the manufacturer. – Uwe Mar 25 '22 at 11:05

Resistor tolerance only refers to the initial nominal value.

All other effects are either unspecified or specified separately. Typically, basic "non-precision" resistors will only specify maximum tempco, in ppm/C. Resistors targeted for precision applications will also specify the curvature of the tempco, voltage coefficient of resistance, aging, etc.
