Thermoelectric cooler ( TEC) is solid thermoelectric effect. Comparing with traditional cooling method, TEC has obvious different features, simple structure, no moving parts, no vibration, no wear, high reliability, long service lifetime, etc. Whats more, TEC starts fast and it is flexible to control TEC. The following is the physical photo of TEC. Figure 1. The photo of TEC Based on TEC, Peltier controller is built to control temperature, as shown in Figure 2. Because of compact size, there is...(more)
Peltier controller is an electronic module which is designed for regulating the thermal load temperature. By using a Peltier module, the temperature of the thermal load can be increased or decreased, which depends on the current direction going through the two terminals of the TEC. Peltier controller can regulate the temperature of the thermal load with high efficiency and accuracy. Here is a popular Peltier controller in US and global market, TEC5V6A-D. This Peltier controller comes with a 90%...(more)
For a temperature regulating system, NTC thermistor is very important as the temperature sensor. Glass encapsulated thermistor has better performance than epoxy coated thermistor, such as zero short and long term drift, which is an important factor in order to achieve high system performance. Low cost epoxy coated NTC thermistor have large short and long term resistance drift, so when sensing the same temperature, the resistance changes with time, it will lead to a wrong sensed temperature, resu...(more)
Thermistor is a kind of sensitive elements. According to different temperature coefficients, thermistor can be divided into positive temperature coefficient thermistor (PTC thermistor) and negative temperature coefficient thermistor ( NTC thermistor ). The typical characteristic of thermistor is temperature sensitive. With temperature increasing, the PTC thermistor resistance will increase and the NTC thermistor resistance will decrease. PTC thermistor and NTC thermistor both belongs to semicond...(more)
Based on Peltier effect, thermoelectric cooler (TEC) is built, which can both heat and cool, depending on the direction of DC current. TEC is a heat transfer tool. It has many advantages such as no refrigerant, high precision temperature control, compact size and so on. TEC has been widely used for temperature control of laser system temperature, refrigeration, water heater, air conditioner and computer CPU, etc. The working state of TEC is based on the current direction and size. In order to re...(more)
SMT Inductor Kits are designed for electronic designers in collecting and organizing surface mount inductors. We have a few types of inductor kits, which contain different inductors of commonly used values, with different quantities. These inductor kits offer a simplest way for obtaining any value of inductors within the shortest time with the highest efficiency. There are 128 individual compartments inside the inductor kits. Each compartment holds a certain amount of inductors of a certain valu...(more)
Thermistor with negative temperature coefficient is called NTC thermistor . NTC thermistor is made of such metal oxide materials as manganese, cobalt, nickel and copper, etc., with semiconductor. NTC thermistor has compact size, resistance and temperature characteristics with small fluctuations, etc. As NTC thermistor has fast response to all kinds of temperature changes, it can be used to realize high sensitivity and high precision detection. Some thermistor with positive temperature coefficien...(more)
We are introducing an easy and convenient way to organize and sort out SMT inductors. Tiny and precise SMT components like SMT inductors, resistors and capacitors, are very common in electronic designers bench, but its hard to organize them in a small place. In order to save time and space, ATI provides a smart way for this: Super Surface Mount Inductor Kits . These inductor kits contain various values and quantities of inductors, which come from renowned inductor manufacturer, such as TDK, Viki...(more)
