What is the difference between the different types of thermistor? I'm talking about the differences between Type J and Type 2 for instance, and not talking about NTC vs PTC.

Edit: I'm not looking for a difference between two specific parts or types, but rather the difference between all the types in general. I chose Type J and Type 2 solely because they were the first two to come across my desk.

edit2: Example Type J Thermistor

  • \$\begingroup\$ I'm wanting a more general answer, and less so about specific parts. I see a lot of different "types" of thermistor in my day to day work and the type is currently meaningless to me, and Google searches haven't been very helpful \$\endgroup\$ – CraigC May 19 '17 at 15:20

    \$\begingroup\$ Afaik "Type J" is a thermocouple not a thermistor. \$\endgroup\$ – brhans May 19 '17 at 15:39

    \$\begingroup\$ Speak to that supplier about curve J - it doesn't sound like anything generic to me. \$\endgroup\$ – Andy aka May 19 '17 at 15:54

The designation is specific to that vendor most likely. Their curve J is an NTC with B25/B85 = ~3977K which is a really common characteristic.

Some other manufacturer may make a thermistor with a really similar characteristic but will have some other designation (or none at all) for the curve.
