NTC THERMISTOR
OUTLINE
This is a Negative Temperature Coefficient Resistor Whose
resistance changes with ambient temperature changes.
Thermistor comprises 2or 4 kinds of metal oxides of iron,
nickel,cobalt, manganese and copper, being shaped and
Sintered at high temperature(1200 to 1500 )
Critical Technical Parameters of NTC Thermistor
Rt---Resistance Value at Zero-power
It's a resistance which is got at a fixed temperature on a
basis of a testing power which causes resistance to Vary in a
range which can be ignored in relation to the total testing eror.
R25---Resistance Value at Rated Zero-power
The design resistance of the thermistor usually refers to the
resistance value got at Zero-power at 25 , which is usually
indicated on the thermistor.
B Value
B value stands for the thermal exponent at a negative
temperature coefficient. lt's defined as a ratio of the balance
between the natural logarithms of resistance values at zero-
power to the balance between the reciprocals of the two
temperatures.The formula is as below:
B=ln RT1 / ( 1 1 =) T1 T2 ln RT1
Rt2 T1 T2
T2 T1 RT2
In this formula: RT1 is the resistance at Zero-power when the
temperature is T1
RT2 is the resisrtance at Zero-power when the temperature is
T2 Unless otherwise specified, B value is got by calculating
the Zero-power resistances at 25 ( 298.15K ) and50
( 323.15K ) . It's not a firm constant within the range of
working temperature.
Resistance-to-Temperature Coefficient at Zero-power
It refers to the ratio of changes of a thermistor. Resistance
value at Zero-powerwhen The temperature, to the resistance
value at Zero-power The formula is as below:

In this formula, " " stands for the resistance-temperature
coefficient at Zero-power when the temperature is T:
RT stands for the resistance value at Zero-power when the
temperature is T
T stands for thetemperature(in K)
B stands for B value
