Learning 101 Thermistors

[MEXICOWANDERER]

Too old of dog... 😞

Thermistor range needed hopefully near zero but 10 ohms will do fine.

Upper resistance 200 ohms

Inverse operation. Meaning lower temperature to 0°F the lower the resistance.

Upper range 200 ohms at 50c or 122°F.

Of couse I can use a pull-up resistor within reason.

I need to narrow the performance window then concentrate on getting a bullet proof package. A thermistor to be glued or screwed onto a battery lug with leads to a weather pack terminal.

I forgot to bring my Newark catalog. Too many sites encourage contact with a traveling salesman. Tacos over techtalk?

Thank you and yes the thermistor is for what you think it is...the power supplies.

A part number and spec sheet would be wunderbar...

Thank You

Thermistors do NOT have a true linear relationship between temperature and resistance. At extremes they are non-linear. If you range is 0F - 122F, you should have no problem.

(Automotive thermistors are not very accurate below about 0F or above about 240F.)

Woo woo. Thank you. Now to cross reference to an armored model with mounting tab.
