2. B-Constant

Measured by zero-power in specified ambient temperatures.R=R0 expB (1/T-1/T0) ..............(1)R: Resistance in ambient temperature T (K)(K: absolute temperature)R0: Resistance in ambient temperature T0 (K)B: B-constant of Thermistor

as (1) formulaB=Rn (R/R0) / (1/T-1/T0) ............(2)

3. Thermal Dissipation Constant

When electric power P (mW) is spent in ambient temperature T1 and thermistor temperature rises T2, there is a formula as followsP=C (T2-T1) ..................(3)C: Thermal dissipation constant (mW/C)Thermal dissipation constant is varied with dimensions, measurement conditions, etc.

4. Thermal Time Constant

Period in which Termistor's temperature will change 63.2% of its temperature difference from ambient temperature T0 (C) to T1 (C).

5. Rated Electric Power

Shows necessary electric power that Thermistor's temperature rises 100C by self heating in ambient temperature 25C.

6. Permissive Operating Current

It is possible to keep Thermistor's temperature rising max. 1C.

1. Resistance - Temperature CharacteristicsPOSISTORr has three main characteristics.

Although there is a negligible difference between the normal and "Curie Point" temperature, POSISTORr shows almost constant resistance - temperature characteristics. Yet they have resistance - temperature characteristics that cause resistance to sharply increase when the temperature exceeds the Curie Point.The Curie Point (C.P.) is defined as temperature which the resistance value is twice the one at 25 C.

2. Current - Voltage Characteristics (Static Characteristics)

This shows the relation between applied voltage when voltage applied to POSISTORr causes balancing of inner heating and outer thermal dissipation and stabilized current. This has both a maximum point of current and constant output power.

3. Current - Time Characteristics (Dynamic Characteristics)

This shows the relation between current and time before inner heating and outer thermal dissipation arrive at equilibrium state. This features having large initial current and abruptly continuous attenuating portion.
