NTC is the abbreviation of negative temperature coefficient, which refers to semiconductor materials of devices with large negative temperature coefficients. NTC thermistor is made of manganese, cobalt, nickel and copper and other metal oxide by ceramic manufacturing process. At the regular temperature, the range of NTC thermistor range is 10~1000000 and temperature coefficient is -2%~-6.5%. NTC thermistor has been widely used for temperature measurement, temperature control, temperature compens...(more)
With the development of technology and economy, thermal silicone pads have been widely used for electronic products, auto mechanics, computers, DVD, VCD and some other products, which need filling materials and heat dissipation. Thermal silica is a kind of thermal interface materials based on silica gel, metal oxide and other auxiliary materials. The main function of thermal silicone pads is to transfer heat by the gap. At the same time, it can also play roles of insulation, shock absorption and...(more)
With the promotion of computer performance, power consumption of CPU is increasing constantly. Due to technology improvement, the power consumption has been alleviated, but because of the enhancement of graphics performance, CPU power consumption is proportional to its performance. Therefore it is still a worthy of our attention that the power consumption is too large to result in higher temperature. Now there has been a very high degree of concern about the heat dissipation problem, however, th...(more)
II. The performance of thermistor With higher and higher precision requirement for temperature measurement and more and more harsh measurement environment requirement, high stability and precision thermistor has been developed and produced. This kind of thermistor has compact size, wide resistance, high precision, and short response time. III. The development of thermistor As the thermistor in high temperature application, it shall has the following conditions: a. Thermistor material is stable;...(more)
In industry and agriculture manufacture, national defense, scientific research and office equipment automation fields, temperature is a very critical data. Temperature sensor, i.e. thermistor is a kind of sensor with repeatability and regularity. Among all the temperature sensitive components, thermistor holds a very important position, accounting for 40% of the total temperature sensitive components. According to the characteristics of resistance change with changes in temperature, there are tw...(more)
NTC thermistor is a sensor, which has been widely used in the applications of temperature measure and control. NTC thermistor is small in size, with fast response speed. However, users need to pay attention to the following points when using NTC thermistor. 1. NTC thermistor can withstand thermal shock of 200℃,but in order not to make thermal diode aging, the rapid changes should be prevented as far as possible for the packaging material is glass. 2. When the current is going through the therm...(more)
ATMC102U is a kind of mini USB color camera , which has been widely used for medical care, microscope, video conference, video phone, multimedia computer toys, industrial pipe and bottom inspection, CCTV safety supervision and other applications. There are two parts in this camera: a camera head and an USB video converter.The former has analog video / audio output signal and it is easy for the latter to connect to the computer, which can convert analog signals into digital signals.Between the tw...(more)
