THERMISTOR

"Thermistor" is the generic name given to thermally sensitive resistors.

Negative temperature coefficient thermistor is generally called as thermistor. Thermistor is a semiconducting ceramic resistor produced by sintering the materials at high temperature and made mainly from metal oxide.

Depending on the manufacturing method and the structure, there are many shapes and characteristics for various purposes such as temperature measurement, temperature compensation and etc.

The thermistor resistance values, unless otherwise specified, are classified at a standard temperature of 25 C.

B constant is calculated from the resistance values at 25 C and 85 C.

Resistance -Temperature Characteristics

The resistance of a temperature is solely a function of its absolute temperature. Since electrical power being dissipated within a temperature might heat above its ambient temperature and thereby reduce its resistance, it is necessary to test for resistance with temperature. The resistance so measured is called RT, which means the resistance at essentially zero-power.

The mathematical expression which relates the resistance and the absolute temperature of

a thermistor is as follows:

Where: Ra is the resistance at absolute temperature T1 Rb is the resistance at absolute temperature T2

Bis a constant which depends on the material of the thermistor

Unless otherwise specified,all values of B are determined from measurements made at 25 C and 85 C.

The temperature coefficient of resistanceis expressed in the following equation:

Dissipation factor

Dissipation factor ( ) is power in milliwatts required to raise thermistor temperature 1 C.

Measured with thermistor suspended by its leads in a specified environment.

HIGH PRECISION THERMISTOR

AT THERMISTOR

The AT thermistor is a high-precision thermal sensing device featuring 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 temperature precision of 0.3 C. Temperature indicators and control instruments are now available for use with the thermistor.

SURFACE MOUNT TYPE THERMISTOR

HT THERMISTOR

HT thermistors are entirely new type of thermistor for surface mounting (by reflow soldering) and were acquired from advanced technology.

Our HT thermistors are adapted metal electrodes packaged in a resin mold, unlike conventional chip thermistors, and can offer 2% tolerance for a resistance value at 25 C.

HT series (SMD Thermistor) is not only compactsurface mounting type but also highly accurate and reliable.

*1	R25 : Rated zero-power resistance value at 25 C.
*2	B value : determined by rated zero-power resistance at 25 C and 85 C.
*3	Time when thermistor temperature reaches 63.2% of the temperature difference. The value is measured in the air.
	Other resistance is available, please ask.
