Thermistor Resistance Chart

Thermistor Resistance Chart - They are often used as a temperature sensor. Web bapi thermistors are thermally sensitive resistors known for exhibiting a large change in resistance with only a small change in temperature. Web the a, b and c constants for each of our thermistor selections can be found in table 1. Web ntc thermistors are usually characterised by their base resistance at room temperature, that is 25 o c, (77 o f) as this provides a convenient reference point. Feel free to bookmark this page for future reference! This web page will be revised as needed to add new and suggested thermistors. Web bapi thermistors are thermally sensitive resistors known for exhibiting a large change in resistance with only a small change in temperature. It is the point on the curve after which the temperature coefficient turns positive. The term thermistor is a contraction of the words thermal and resistor. Negative temperature coefficient (ntc) thermistors have a resistance which reduces as the temperature rises (fig 1.).

The Heat Dissipation Constant Is An Expression In Milliwatts Of The Power Required To Raise The Temperature Of A Thermistor 1°C Above The Ambient.

Precon type iii precon type iv. Using these constants with the above equations, you can determine the temperature of the thermistor based on its resistance, or determine a thermistor’s resistance at a particular temperature. Of teflon encased thermistors add 100 to part no. They are used for resistance thermometers in temperature measurement and all sterling sensors assemblies are made using this type of thermistor.

44005 Is A Standard Thermistor.

At 100°c, resistance is 138.50 ohms. All resistors have some dependency on temperature,. The term thermistor is a contraction of the words thermal and resistor. This web page will be revised as needed to add new and suggested thermistors.

Web Bapi Thermistors Are Thermally Sensitive Resistors Known For Exhibiting A Large Change In Resistance With Only A Small Change In Temperature.

44105 is a teflon encased thermistor with the same resistance values. Web below are tables and graphs for thermistors commonly found in appliances. So for example, 2k2ω at 25 o c, 10kω at 25 o c or 47kω at 25 o c, etc. Negative temperature coefficient (ntc) thermistors have a resistance which reduces as the temperature rises (fig 1.).

It is the point on the curve after which the temperature coefficient turns positive. Bapi thermistors are thermally sensitive resistors known for exhibiting a large change in resistance with only a small change in temperature. Another important characteristic of a thermistor is its “b” value. ±0.15°c @ 0°c (±0.28°f @ 32°f).
