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---Zero Power Resistance  
NTC  
Rt  
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 ---Rated Zero Power Resistance  
R25  
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 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:

RT2 is the resisrtance at Zero-power when the temperature is
