Introduction to PTC thermistor resistance
PTCR (POSITIVE TEMPARATURATURATURATUFIFINT of Resistance) is a
thermistor with a strong temperature characteristic, which is
mainly composed of Batio3. BATIO3 ceramics is a typical iron
electrical material, which is greater than 1012Ω · cm. After the
conducting doping, the strong PTC effect shows that the normal
temperature resistance is very low. As the temperature rises,
mutations have occurred near Juri Point, resulting in several
magnitude changes. This is because the grain boundary of the
polycrystal BATIO3 semiconductor material has a potential layer
caused by the surface state. At the temperature of the Curie, the
crystal boundary has iron electrical, the dielectric constant is
very large, the potential height is low, the electrons are very
high, and the electrons are very high. It is easy to pass through
the potential barrier, the corresponding material resistivity is
small, but when the temperature of the Curie is above the
temperature, the crystal layer changes, the iron electrical
disappearance, the dielectric constant decreases sharply. The
potential is rising. With the sharp increase in the height of
potential barriers, it is difficult for electrons to cross the
power, and the resistivity of the corresponding materials has risen
sharply, and the PTC effect of the material is macroely manifested.
Due to the characteristics of the PTC thermistor, whether in
industrial electronic equipment or household appliances, thermistor
resistance has been widely used. The basic parameters are shown in
the figure.
The figure below:
TC Curry Temperature: It is the starting point of PTC semi
-porcelain change. Generally, the temperature point corresponding
to the PTC component RMIN twice the resistance value;
TMAX maximum temperature: the corresponding temperature when the
component reaches the highest resistance;
TP maximum working temperature: upper limit temperature within the
scope of work;
TMIN minimum temperature: The temperature when the component
(normal) presents the minimum resistance;
T25 standard room temperature 25 ° C;
RC switch resistance: that is, the corresponding resistance when
the temperature of the point is at the temperature;
RMAX maximum resistance: the maximum resistance that the component
can reach;
RP maximum working resistance: the resistance corresponding to the
upper limit working temperature;
RMin minimum resistance: component (normal) minimum resistance;
R25 room temperature resistance: When the standard room
temperature, the resistance corresponding to the component.
