General
Aolitel leadless disc NTC thermistors offer excellent thermal and electrical stability with wide range of resistance values customizable based on material properties and customer requirements. These parts are ideal for various general purpose and automotive (AEC-Q200) applications. Available in custom disc sizes and multiple temperature stability options.
This type of product is widely used in automotive and consumer applications. They are assembled in custom-probes for sensing the temperature of liquids (water, oil, ...), gases or surface of any other component. The metallization covers completely the surfaces of the thermistor. The particularly flat and smooth surfaces ensure an excellent electrical and thermal contact under pressure.
Typical Applications
Temperature sens ing and measuring in automobi le cool ing system, combus tion engine, larger power electric engine, oil transformer etc . Also applicable for temperature meausing on other occasions.
Ambient temperatur sensing, control and compensation
Liquid or gas temperature contol and monitoring
Assembly into probes
Automotive (air conditioning, temperature monitoring, heated seat, oil temperature control, others)
Fire detecting systems
Chemical industry

DESIGN OF THE THERMISTOR
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.

Remarks: Custom design for different RT curve and mounting configuration available
Choice of the tolerances
The precision of the temperature measurement determines the calculation of the tolerance on the resistance: R/R = (%/°C). T (°C)
For example, the NTC NR55--3049-99, using “N5” material (R (T) characteristic displayed on page 31), requires a precision of 1°C over the temperature range 110°C - 120°C.
The tolerances can be calculated: R110°C /R110°C = 1°C* 2.91%/°C = 2.91% R120°C /R120°C = 1°C* 2.76%/°C = 2.76%
