Disc NTC Thermistor MF57 For Automotive Engine Coolant Water Tank Temperature Sensor
I Application Of The Disc NTC Thermistor MF57
It is mainly applied as temperature-sensing component used in order-spot temperature
measuring in the cooling system of automobile, combustion engine, huge electric power
engine, oil transformer and so on, also be capable applied in temperature measurement
in other conditions.
1, Rechargeable batteries and CPU.
2, LCD,Crystal oscillator
3, Temperature compensation
4, Temperature sensing for various types of circuits.
II Characteristics Of The Disc NTC Thermistor MF57
Small tolerance range for resistance and B value, good coherence and interchange,it
can match all kinds of auto meter no matter domestic brand car or overseas brand car.
MF57 Series thermistor used for automotive electronics (diesel locomotive, large motor,
oil-immersed transformer) of the cooling system for fixed point temperature sensing
element, temperature measurement can also be applied to other places.

VI DESIGN Of The Disc NTC Thermistor MF57
Choice of the resistances If the application is to measure the temperature around a defined point, a unique nominal resistance can be chosen (for example, among standard values of the ND range products presented on pages 20 to 24).
When it is required to measure the temperature over selected ranges T1 –T2 , T2 –T3 , ..., the corresponding resistance R1 , R2 , R3 , ..., must be such that they can be located on the R (T) characteristic of an existing NTC material (for example among standard materials whose R (T) are displayed on pages 29 to 33).
The resistances must also be compatible with the resistivity of the material and the dimensions of the thermistor.
