Thermoelectric cooler (TEC) plays an important role in its application products. According to the characteristics, weakness and application range, the following problems should be determined when selecting TEC.(more)

When we mention peltier controller, we need to focus on peltier. Peltier comes from a Peltier effect, which was discovered by a French physicist, Jean Charles Athanase Peltier, in 19th century. Peltier is named after his surname. Peltier effect is also called thermoelectric effect, which converses temperature difference to voltage and vice versa. When there is a temperature difference on each side of a TE device, it creates voltage, and this TE device is called TEG. TEG can be used to generate electricity, but it has limited capacity due to low power. When there is a voltage difference on each side of a TE device, it creates a temperature difference, and this TE device is called TEC. TEC is now widely used in thermal system, such as solid state lasers, refrigerator, optical components, etc.(more)

Thermoelectric cooler (TEC) is also called semiconductor cooler, which is using an artificial cooling technology based on Peltier effect. At present, the focus of domestic and foreign researches is on the characteristic optimization of TEC itself thermoelectric materials, but there are few researches on the combined influence of TEC performance. The main integrated influence factors of TEC internal structure include geometry size of the thermoelectric arm, contact effect and so on.(more)

ATFC105D is a digital TEC/fan controller, which is designed to regulate the temperature of an enclosed chamber.(more)

Super SMT inductor kit is a very popular product of Analog Technologies, Inc, which has been in US market and overseas market for many years. This inductor kit contains various types and quantities of SMT inductors, so you can select a proper one by its part number. For example, L0402-74VALUE-20PC represents that there are 74 values of inductors; the inductor size is 0402, and for each value, there are 20 pcs of inductors. It's easy to choose our inductor kits by its part number. Generally, we provide 0402, 0603, 0805, and 1008 size of inductors; there are 74 values, 88values, 85 values, and 60values; for each value, we provide 20pcs, 50pcs, and 100pcs. It can meet general need.(more)

The MTBF for standard TECs is at least 200,000 hrs, which is based on relatively stable running conditions, with several times ON/OFF per day during operation. However, in other applications, the power is frequently on/off, especially in constant temperature controller application. There is a test for research the influence of the on/off switch cycle to the TECs in a constant temperature. Install the TEC module with silicon grease between a couple of convector radiators. The load time of the current is 7.5s, and the breaking time is 7.5s, thus a cycle is 15s. During the cycle, monitor the input current of each TEC module. The mark for failure is that the resistance of TECs increases, resulting in the current decreases. The test takes about 25,000 hrs with at least 6 millions of cycles. Under this condition, the MTBF is 125,000 hrs, or 3*107 times of on/off switch cycle.(more)

With the popularization of fuzzy logic technology, a lot of kitchen equipment, such as microwave oven, electric cooker, disinfection cabinet and so on, have adopted NTC thermistor temperature sensor, which has high sensitivity, heat shock resistance, no pollution and some other advantages. The NTC thermistor temperature sensor can realize the set of program control, heating, heat preservation, cooling, power failure and other functions.(more)

Thermoelectric generator (TEG) is built based on Seebeck effect to convert heat directly into electricity. In the open circuit composed with two different conductors, if there is temperature difference on the two contact points of the conductor, electromotive force will come into being in this open circuit. The polarity of the output voltage depends on the polarity of the temperature difference on both ends of the TEG. If the hot end and the cold end of TEG are swapped over, the polarity of the output voltage will change.(more)

ATH100K1R25 series thermistors have three versions, ATH100K1R25, ATH100K1R25T70 and ATH100K1R25T70S. ATH100K1R25 has two bare leads; ATH100K1R25T70 has two leads covered with high temperature plastic tubing, non-sealed; and ATH100K1R25T70S comes with leads covered with plastic tubing, sealed.(more)

AAS20A5V is a kind of high efficiency AC input 20A 5V laser driver, which is used to drive 0~20A laser diode. 0~20A output current can be set by setting 0~2.5V analog voltage. It has been widely used for driving fiber diode, diode laser rod and so on. The physical figure of AAS20A5V laser driver is shown in Figure 1.(more)
