Using the same formula and chosen temperature you can establish the third point.

Ntc resistor r85. Thermistorresistance junction voltage values for fig 1. This is a property of a negative temperature coefficient resistor ntc for short. 10000 tape reel tr alternate packaging.

5 4 a to vde 0660 ac3. The resistance of ntc will decrease as the temperature increases. Beta can be assumed to be constant between the two test endpoints.

This is a simple online calculator for color band resistor marking inductor color band marking ceramic or tantalum capacitor 3 digit marking and smd resistor 3 digit 4 digit 10 5 2 and eia 96 e96 1 tolerance code marking. Thermistor ntc 10kohm 3380k 0402 330000 immediate available. For temperature measurement and control applications negative temperature coefficient ntc.

18240 w b 4200 perm. Vishay intertechnologys ntc negative temperature coefficient thermistors portfolio includes refrigerator sensors flex foil sensors miniature immersion sensors steel capped sensors long immersion sensors with connectors standard lug sensors thermal gradient lug sensors mini lug sensors screw threaded sensors ice cube sensors mini chip sensors with flexible leads a variety of. Required temperature sensor ntc resistor r85.

An ntc thermistor is a thermally sensitive resistor whose resistance exhibits a large precise and predictable decrease as the core temperature of the resistor increases over the operating temperature range. R2 r1 exp b1 t1 1 t2 thus r85 14513 and now you have two points. The 3 digit smd resistor code r85 stands for 085 w in words.

Voltage divider circuit calculator for ntc thermistor. The manner in which the resistance decreases is related to a constant known in the electronics industry as beta or ss. 15 0c above the selected release temperature perm.

There are also thermistors that have positive temperature coefficient ptc for short which means as the temperature increases the resistance increases. A thermistor is an electronic temperature sensing device which exhibits a change in resistance with a relative change in temperature. Given for device ttf 103.

Switching current for release contact max. 330000 003582 10000 minimum. Enter the fixed resistor and vsupply click calculate.

The name derives from two other words thermal resistor. 60 w release temperature selectable with slide switch p 65 0c or 130 0c setpoint fixed approx. 200 w required heat output min.

Zero point eight five ohms resistance. As you can see the temperature gets hotter the resistance is lower.
