THERMISTOR0Thermistor0 is the generic name given tothermally sensitive resistors.Negative temperature coefficient thermistoris generally called as thermistor. Thermistoris a semiconducting ceramic resistorproduced by sintering the materials at hightemperature,and mades from metal oxide asits main component. Depending on the manufacturing methodand the structure, there are many shapesand characteristics of thermistors, which isutilized for various purpose such astemperature measurement, temperaturecompensation and etc.The thermistor resistance values, other thanthose especially noted, are classified at astandard temperature of 258CB constant is value calculated from theresistance values at 258C and 858C.

The resistance of a temperature is solely a functionof its absolute temperature. Since electrical powerbeing dissipated within a temperature might heatabove its ambient temperature and thereby reduceits resistance, it is necessary to test for resistancewith temperature. The resistance so measured iscalled RT, which means the resistance at essentiallyzero-power.The mathematical expression which relates theresistance and the absolute temperature ofa thermistor is as follows:

Ra5Rb exp B 1T1

1T2

BT2

2

Ra T1Where: is the resistance at absolute temperatureis the resistance at absolute temperatureRb T2

B is a constant which depends on thematerial of the thermistor

Unless otherwise specified,all values of B aredetermined from measurements made at 258C and858C.The temperature coefficient of resistancea is expressed in the follow ing equation:

3100(%/ 8C)a52

AT THERMISTORThe AT thermistor is a high-precision thermal sensing device featuring an extremely small B-value tolerance and resistance.When used as a temperature gauge, the AT thermistor requires no adjustment between the control circuit and the sensor. This insures a temperature precision of 60.38C.Temperature indicators and control instruments are now available for use with the thermistor.

To bend the lead wires, secure the lead wires at least 3mm away from the base of the epoxy coat by a cutting pliers and etc. and then bend the lead wire side, but not the epoxy coat side.

Eliminate any event and/or circumstance where more than 2N pressure is applied to the lead wires in the direction shown by the arrow or where the lead is spread wide more than 60.3mm from the original position.

Connect the FTs to the electrodes using conductive epoxy resins.The FTs cannot be soldered onto the electrodes.

SMD type chip Chip thermistors are specially processed, highlyreliable thermistors. They can be face-bonded to act as thermal compensators for ICs and they are manufacturedin sizes down to 1 square mm, they can also be used to detect temperature with relatively smalltime constants.
