PTC (Positive Temperature Coefficient)
PTC (Positive Temperature Coefficient) thermistor ceramics is a class of semiconductor functional ceramics with a positive temperature coefficient. PTC in the transition temperature (Tc) before the resistance with the increase in temperature and decline; temperature from the transition temperature to the thermal runaway temperature, the resistance with the increase in temperature and a significant increase in resistance, which is the PTC effect. The use of the PTC effect, according to different temperature coefficients can be manufactured different temperature coefficients, can be manufactured for different purposes of the PTC thermal ceramic PTC components have the advantages of high reliability, ease of use, safety, power saving and so on. This is widely used in household appliances, power facilities, electronic equipment and automotive industry and many other fields. PTC element applications according to its own characteristics can be divided into three categories, namely, resistance temperature characteristics of the application, the application of the current time characteristics and voltage and current characteristics (volt-ampere characteristics) of the application.
1.Resistance-temperature Characteristics
The resistance-temperature characteristic of a PTC element refers to the relationship between the zero-power resistance value of the element and the temperature of its resistive body at a specified measurement voltage. R-T characteristic diagram on the left. In the figure, group A is high Curie point PTC thermistor (Tc≥120℃), group B is low Curie point. type A is generally used as temperature sensing, overheating protection, motor starter and high temperature heaters, etc. type B is generally used as temperature sensing, overcurrent protection, time delay components and automatic degaussing devices.
2.Current-Time Characteristics
The current-time characteristic of a PTC element is the relationship between the current I flowing through the element and the time T when the rated operating voltage is applied to both ends of the PTC element. Typical applications of the current-time characteristic are such as automatic degaussers, motor starting, delay switches, etc.
3.Voltage-current characteristics
Voltage-current characteristics, also known as volt-ampere characteristics, refers to the relationship between the voltage across the sample and its steady current in still air at room temperature. As can be seen from the figure, the curve consists of AB, BC ends: AB section of the resistance is basically unchanged, the component self-heating temperature rise is not high. bc in the vicinity of the switching temperature. The PTC thermistor is connected in series with the load, properly select the resistance value and working condition. Can play a current protection role in the heat of the PTC element. In a certain voltage and standard environment, the measured stable temperature is called the PTC surface temperature (Ts). When in use, PTC in a very small range centred on the surface temperature, power-environment to achieve dynamic equilibrium, to achieve automatic temperature control. According to the needs of different applications, adjusting the process and formula, you can manufacture PTC elements with different surface temperatures in different resistance ranges.
PTC heating element is a modern and future high-tech product. It is widely used in light industry, housing, transport, aerospace, agriculture, medical care, environmental protection, mining, civil equipment and so on. Compared with nickel, wire, or far-infrared heating elements, it has excellent advantages.
When applying AC or DC voltage to the PTC element to raise the temperature, at the Curie point temperature, the resistivity is very low; when once beyond the Curie point temperature, the resistivity suddenly grows, so that its current drops to a stable value. To achieve automatic temperature control, constant temperature purpose.
PTC element heating without red, no open flame (resistance wire heating with open flame), not easy to burn. PTC element around the temperature beyond the limit value, the function of its automatic decline to the equilibrium value. There is no danger of combustion.
The energy input of the PTC element is proportional and current-limited, which saves power compared to the switching energy input of heat generating components such as inlays.
PTC element itself is an oxide, without the disadvantages of high temperature oxidation of the inlay wire, and no infrared tube fragile phenomenon, long life.
The PTC element itself controls the temperature automatically, so there is no need to add a separate automatic temperature control circuit device.
