NTC thermistor plays a vital role in many applications, due to its characteristics: the resistance decreases with the increase of the temperature and the resistance increases when the temperature falls. There are some application examples of NTC thermistor.(more)

Peltier cooler ATE1-07 has 7 pairs of Peltier elements, with a maximum input voltage of 0.9V. The size of this series TEC modules is small, less than 10mm. There are two ceramic plates on the both side of the TEC module.(more)

ATE1-17 series of Peltier coolers come with 17 pairs of Peltier elements, with a maximum input voltage of 2.2V. There are two insulated lead wires, one is red for positive and the other is black for negative, as shown in the photo below.(more)

The Inductor kit is a research and development product of ATI, which is utilized to store inductive elements. Inductor kits released by our company have high quality and long service lifetime. There are 128 individually lidded compartments, and inductor values are printed on each lid. In order to find inductors easily, the values are arranged in the order from left to right and from top to bottom. Each lid inside is very tight so that internal chip inductors can be ensured not to leak or lose. The following is the photo of an actual inductor kit.(more)

Peltier cooler ATE1-31 has 31 pairs of Peltier elements, with two ceramic plates and two lead wires of different colors. The maximum voltage is 3.9V, and the maximum current is variable due to the height of the Peltier elements. There are several models in this series.(more)

NTC thermistor in series in AC circuit functions like current insurance. How does this insurance do in the circuit? When the circuit is powered on, there produces an instant surge current. Thermistors can suppress this current. After this, the current will keep stable, and then the NTC thermistor will decrease its resistance to an ignorable value, which will not influence the current.(more)

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)
