NTC thermistor refers to thermistors with negative temperature coefficient. When the temperature rises, the resistance of NTC thermistors will decrease, and when the temperature falls, the resistance will increase.(more)

Diode laser drivers are designed to drive diode lasers in a stable and efficient way. Based on different functions, laser drivers are divided into multiple types, among which DC input laser drivers include low noise diode laser drivers, high efficiency constant current laser drivers, high voltage constant current laser driver, constant current laser drivers; and AC input laser drivers.(more)

With the development of science and technology, semiconductor laser technology has penetrate every field of national economy and defense construction. It has been applied in remote communication, laser radar, digital signal storage and recovery, laser ranging, robot, holographic application, medical diagnosis, etc. However, It's very demanding for semiconductor laser on its working conditions. If It's under improper work or storage condition, it will result in a sharp deterioration in performance and even failure. Therefore, an electronic power supply for driving diode lasers, i.e. laser driver is playing a more and more important role in making the laser work normally. (more)

A laser driver is between multiplexer and laser, which completes electro-optical conversion function. In order to make the laser work well, the good driving signal needs to be provided, depending on the performance parameters of laser driver.(more)

The main function of laser driver is to enlarge high speed signal outputted by a multiplexer to drive the laser diode to work effectively.(more)

In optical fiber communication, optical module plays a very important role. Laser driver used on the front end of optical emission can realize the laser bias and modulation. High speed voltage signal is converted into high speed current signal to modulate laser.(more)

Thermoelectric cooler (TEC) is built on the thermoelectric system, which can both cool and heat, depending on DC current direction. As TEC has no refrigerant, no pollution, no rotation parts, no noise, long service lifetime and some other advantages, it has been widely used in electronic fields, laser fields and so on.(more)

With the development of science and technology, there are more and more researches about thermoelectric cooler (TEC) and the achievements on the improvement of the material optimal value and the optimization of thermoelectric cooler has been obtained. Now TEC has been widely used in many fields, and along with the time and research development, TEC will play more and more important role in the electronic and some other fields.(more)

Thermoelectric cooler (TEC) is built based on Peltier effect. It is a kind of solid components, which has no pollution, high reliability, small size, rapid cooling, rapid heating and some other characteristics. It has been widely used in electronic, medicine, industry, agriculture and some other fields. However, TEC still has some problems.(more)

High reliability and long life time can be achieved when the thermal cycling times is few, the temperature change range is narrow, upper temperature limit is low, as well as that temperature change is slow. On the contrary, in a wide temperature range, high changing speed, many times cycling, it will shorten the life time of TECs largely. It's noteworthy that the absolute life time of TECs depends largely on the total cycling times, not the total time for the cycling.(more)
