Default Resistor tempco

What resistor types and brands have low temperature coefficient.
Not looking for ultimate expensive stuff.
Just good dependable low tempco.

Easy :
Resistors | Mouser
You can select which ppm/C you want and select after that on price.

Resistor tempco
Bulk foil have very low tempco but tend to the "ultimate expensive" category. Some wirewound types are available with very low tempco. For the money I think it's hard to beat Vishay PTF metal film series, though they are physically large for their power rating, and may not be available in as many values as others.

A rule of thumb is that higher tolerance means lower temperature coefficient. You'll be hard-pressed to find anything lower than .01% tolerance, .005% seems to be a lowest limit and is usually a bulk foil resistor. Vishay's Z-foil resistors are the most stable of all, but command a premium price.

PTF is a very good alternate.

You've not given any indication of how low a tempco you are looking for, "good dependable low" isn't very meaningful. 100ppm/C ? 10ppm/C? what?
