Pretty weird data sheet.

What do you consider weird about it?

You mean that it is supposed to be linear but the graph shows it is not?
Came up 404 for me. This worked:Pretty weird data sheet.

Who ever heard of an RTD that cared about polarity?

Looks like a very well characterised and complete data sheet andOn Fri, 14 Aug 2020 11:36:49 -0500, John S<Sophi.2@invalid.org

A thermistor has an equation. This part has an entire web site.
That is just one of many amusements.

Looks like a very well characterised and complete data sheet and
pretty linear over short ranges. Depending on target app and cost,
could be an improvement over thermistors, where cheap ones have a
wide tolerance...

There are multiple sources for thermistors too.
Lately I\'ve been hanging thermistors on some parts, instead of doing
complex current limiters. A thermistor can be hacked into a MAX809
powerup reset circuit... just shut down the box before something
fries. I\'m thinking that the thermistor equation may allow me to use
two thermistors in parallel. Three would be over the top.

Works fine if you don\'t mind some slop. The resistance decreases by
about 3-4% / K, so if only one of the two devices is overheating, the
trip point would be about 20 K hotter than if the two were at equal
temperatures.
