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.(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.(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 realize constant temperature control automatically, Peltier controller (TEC controller) is designed and produced. Our company (ATI) is very good at designing Peltier controller(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 semiconductor devices.(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, resulting in a drifted target object temperature. You can take some factors into consideration when choosing a proper NTC thermistor in temperature control system: operating temperature range, sensitivity, drift, size, mounting method, etc. Our NTC thermistors are all encapsulated with glass material, with compact size. Some thermistor come with bare leads, while some are lugged form. The former is used for point sensing in order to achieve high accuracy; the latter is for bulk temperature sensing, such as optical components, etc.(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.(more)

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. What’s more, TEC starts fast and it is flexible to control TEC. The following is the physical photo of TEC.(more)

ATI provides a series of Peltier controllers, among which most are low voltage peltier controllers. In order to meet the customers' requirements about high voltage, we have developed a high voltage Peltier controller, ATEC24V10A-D.(more)

NTC thermistor is a kind of thermistors with negative temperature coefficient. As NTC thermistor has a compact size, small fluctuations in resistance and temperature characteristics, fast response for various temperature changes and other advantages, it can be used to achieve a high reliability and high accuracy detection.(more)

Here is more about the Peltier controller ATEC24V10A-D. This Peltier controller provides a high stability low noise 2.5V reference voltage, which is used to set the output current limit and set-point temperature. In addition, it is also used as the voltage reference for external ADC and DAC.(more)
