Advantages and disadvantages of thermistor

There are some advantages of thermistor which are given below.

• The thermistor has fast response over narrow temperature range.
• It is small in size.
• Contact and lead resistance problem not occurred due to large resistance.
• It has good sensitivity in NTC region.
• Cost is low.

There are some disadvantages of thermistor which are given below.

• The thermistor need of shielding power lines.
• The excitation current should be low to avoid self heating.
• It is not suitable for large temperature range.
• The resistance temperature characteristics are non linear.
