ATH10K1R25 series ntc thermistors are glass encapsulated thermistors with high stability and high precision that are popularly applied in temperature sensing for laser diodes, optical components, industrial process control, etc. All of these applications require high temperature sensitivity, long term stability, and/or high sensing temperature.(more)
ATE1-127 TEC Modules have 127 pairs of Peltier elements. The maximum voltage is 15.4V, and there are 17 kinds of maximum current to choose from. The TEC module is used to accurately adjust the object temperature, when working with TEC controller, a highly stable and efficient temperature control system is constituted. ATE1-127 TEC is composed of two pieces of bare ceramic plate with very smooth surface. The ceramic plates can be installed to the flat surface of the metal, and there are a few layers of thermal conductivity of filler material (thermal conduction silicon or conductive grease) between them. When installing, please ensure uniform force so that thermal contact between TEC ceramic and metal will be good, and thermal resistance will be reduced to the minimum.(more)

As shown in Figure 1, TECA1-5V-2.5V-Dis a typical Peltier controller of ATI (Analog Technologies, Inc.). This Peltier controller has an input voltage of 5V and the maximum output voltage of 2.5V. And the Peltier controller is packaged in a metal enclosure, which helps to block the interferences between the controller and other electronics.(more)
In optical fiber communication, optical module function is very important, and laser driver is used for light emission front, which can realize laser bias and modulation. The laser controller converts the voltage signal into current signal with high speed to modulatelaser and generate high-speed light signal. And then the light signal is coupled to the optical fiber transmission.(more)
In recent years, high precision semiconductor laser with continuous adjustable high stability is more and more widely used in military and civilian fields. And the demand of driving power supply used with laser is also becoming more and more. The semiconductor laser driving power supply with excellent quality and high stability and high precision should ensure the laser work safely, anti-interference ability is strong and the laser has the normal service life.(more)
TEC controller is a kind of semiconductor device, which realize the refrigerating and heatingprocess according to the current trend through the TEC.And our TEC controllers are also based on TEC current direction and strength to realize temperature control. By using the TEC controller, we can precisely adjust the temperature of the object. And it has the advantages of high efficiency, high stability, high reliability and small size.(more)
DC-DC converter is a voltage converter that changes input voltageinto output fixed voltage. The DC-DC converter can be divided into three categories: step-up DC-DC converter step-down DC-DC converter and step-up and step-down converter. According to the demand, there are three types of control to choose:PWM with high efficiency has good output voltage ripple and noise; even after long time use, PFM has the advantages of small power consumption, especially when the load is small; PWM/PFM can achieve the control of small load and heavy load.At present, DC-DC converters are widely used in mobile phone, MP3, digital cameras, portable media players and other products.The following introduce is about the principle of DC-DC and design skills.(more)
With the development of science and technology, thermal electric coolers (TECs) have become more and more popular in cooling systems. TECs can both heat and cool at the same time, depending on the direction of the input current. And TECs have many advantages of no pollution, no noise, no wearing, a long life time, and high reliability, etc.(more)
