That is, other than just the nomenclature.

Thermistors have a much higher variation of resistance, a thermistor can change from the 100Ω's to kΩ's (and 100kΩ's) over a range of 100C°.

A tempco resistor usually has its resistance change by 100ppm's or 1000ppm's which would be less than an ohm over a 100C° range

  • \$\begingroup\$ You can use HTML ° for the degrees symbol. Also Ω and μ are handy. The are not rendered in the comments. \$\endgroup\$ – Transistor Apr 16 at 22:13
  • \$\begingroup\$ Why would you ever use a tempco then and not an RTD? I didn't even know tempcos existed until this question. \$\endgroup\$ – DKNguyen Apr 16 at 22:24
  • \$\begingroup\$ Temp comp of log amps is one application that comes to mind. \$\endgroup\$ – sstobbe Apr 16 at 22:36

    \$\begingroup\$ If you need only a small linear change, then use a tempco. If you need to keep a parameter of the circuit within tolerance then a tempco can help with that. \$\endgroup\$ – Voltage Spike Apr 16 at 22:48
  • \$\begingroup\$ Also if you want a degree symbol that does render in comments, backslash, string, hat, backslash, "circ", backslash, string. Gives you \$^\circ\$. Hope that makes sense. Not sure how to write mathjaxx commands without them appearing rendered. \$\endgroup\$ – K H Apr 17 at 0:27
