Product Description:
NTC Thermistors Key Characteristics
Defined sensitivity to temperature.
Sensitivity to electrical power
input.
Sensitivity to changes in thermal conductivity.
NTC Thermistors Rt -- Zero Power Resistance Value
The resistance value measured at a fixed temperature by adopting sufficiently low power consumption.
NTC Thermistor R25 -- Rated Zero-power Resistance Value .
As defined by IEC 60539, NTC (Negative Temperature Coefficient) thermistors are thermally sensitive semiconductor resistors which show a decrease in resistance as temperature increases. With -2%/K to -6%/K, the negative temperature coefficients of resistance are about ten times greater than those of metals and about five times greater than those of silicon temperature sensors.
Changes in the resistance of the NTC thermistor can be brought about either externally by a change in ambient temperature or internally by self-heating resulting from a current flowing through the device. All practical applications are based on this behavior.
NTC thermistors are made of polycrystalline mixed oxide ceramics. The conduction mechanisms in this material are quite complex, i.e. either extrinsic or intrinsic conduction may occur. In many cases NTC thermistors have a spinell structure and then show valence conduction effects.
NTC Thermistor Dissipation Factor δ
NTC Thermistor dissipation factor δ is defined as the ratio of the change in power dissipation and the resultant change in the thermistor's body temperature. δ =ΔP/ΔT. δ changes in response when the ambient temperature changes, within the working temperature range.
NTC Thermistors Thermal Time Constant
NTC Thermistor Thermal Time Constant is the time required by a thermistor to change 63% of the difference between its initial and final temperature.
