Basic Characteristics of NTC Thermistor
Measured by zero-power in specified ambient
temperatures.
R=R
R: Resistance in ambient temperature T (K)
(K: absolute temperature)
R
B: B-constant of Thermistor
as (1) formula
B=Rn (R/R
When electric power P (mW) is spent in ambient
temperature T
there is a formula as follows
P=C (T
C: Thermal dissipation constant (mW/ C)
Thermal dissipation constant is varied with dimensions,
measurement conditions, etc.
Period in which Termistor's temperature will change
63.2% of its temperature difference from ambient
temperature T
Shows necessary electric power that Thermistor's
temperature rises 100˚C by self heating in ambient
temperature 25˚C.
It is possible to keep Thermistor's temperature rising max.
1˚C.
