Analog Technologies has developed and launched a brand-new variable resistor and capacitor box, ATRCT101, an anticipated member of the adjustable decade box family.(more)

We have released various resistor kits throughout the years, including differential resistor kits, new resistor kits with SK200 enclosures, and resistor kits containing 1% or 5% accuracy resistors.(more)

What is the area of 14mm*14mm? Almost as small as your thumbnail. What can we do with a space as small as your thumbnail? We can make a TEC controller. This is an innovation of both size and price, a game changer of TEC controller field.(more)

In the installation process, it's necessary to avoid wrong installation, which makes influence to the TEC modules. There are the following points that may affect the reliability of the TEC modules during the installation:(more)

Thermoelectric cooler (TEC) is based on “Peltier effect”, which can both cool and heat. According to changing the polarity of direct current, the same TEC can realize cooling or heating. This effect is achieved by the principle of thermoelectric. In principle, TEC just plays a role of a heat transfer tool.(more)

Thermoelectric coolers (TECs) are built based on Peltier effect, which can both heat and cool depending on the direction of input DC current. Because of having no noise, no vibration, no refrigerant, light weight, compact size and some other advantages, TEC has been widely used for cooling certain components in electronic devices and radio communication equipment.(more)

It can be seen as the reliability test for TECs to make continuous thermal cycling to TECs in a wide temperature rang. Especially temperature of TECs in this process rises to very high. Compared with most applications, this process will cause higher failure rate. Most of failures are rooted in unmatched thermal expansion coefficients of thermal materials and other components. This is inevitable. It performs as initial failure, but sometimes, performance degeneration will be observed before failure.(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)

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)

Continued from the last article. 5. Determining TEC series Selecting TEC series must meet the actual temperature difference requirements, that is, the nominal temperature difference shall be higher than the actual temperature difference, so that it can meet the requirements. However, the series is not too much because TEC price has great improvement with the increase of series.(more)
