NTC is short for Negative temperature coefficient, which refers to semiconductor or components with high negative temperature coefficient. Therefore, the so-called NTC thermistor is the thermistor with high negative coefficient temperature.(more)

Laser driver is also called laser controller, laser diode driver, which is designed and used for driving diode lasers. The laser drivers of Analog Technologies, Inc are featured compact size, high efficiency, low noise and RoHS compliant. ATLS100MA103 is one of 103 series laser drivers.(more)

Peltier controller is an electric module, which is designed and produced for driving a thermal electric cooler (TEC) to stabilize temperature. Peltier controller has many advantages including compact size, high efficiencyand high reliability. Figure 1 is the physical photo of an actualPeltier controller.(more)

ATE1-71 series TEC modules are applied to regulate the temperature of the target object and widely used in solid state laser, icebox, air condition, IC’s, optical components, CPU’s, CCD cameras, etc. This series of tec modules come with high changing speed and stabilize the temperature to a wide range with high precision.(more)

ATLS200MA103 is laser driver with compact size and low noise, which is designed for driving laser diodes. The noise is very low, 2.5µVP-P at 0.1Hz to 10Hz.(more)

NTC thermistors are widely used in applications of temperature sensing and measurement. In these applications, high temperature sensitivity, long term stability and high reliability are needed. This NTC thermistor, ATH10K1R0, is a glass encapsulated thermistor with two coated leads. It is sealed between the thermistor head and the two leads, which can be used in non-corrosive liquid of up to 250°C for temperature sensing or measurement.(more)

Continued from last article. It needs to be noted that the δ value is the parameter of NTC thermistor before the secondary encapsulation by most of the manufacturers. Although the current determined by this parameter won’t produce self-thermal, but it affects the selection range of the parameter value. That’s because the max. non self-thermal power is increased after secondary encapsulation. The way to determine the current range by dissipation factor is to determine the accuracy of NTC thermistor first, and then the self-thermal power consumption allowed. For example, when the accuracy of NTC thermistor is 0.1°C, then the self-thermal temperature doesn’t exceed 0.1°C, that is to say, less than 0.1δ power won’t produce self-thermal power.(more)

ATH10KR8B series NTC thermsitors are the replacement part of our ATH10KR8B, which has stopped production already. This new NTC thermistor comes with three versions, ATH10KR8B, ATH10KR8BT65, and ATH10KR8BT65S.(more)

ATE1-TC-31-3AS thermal cycling TEC module is newly developed by our company, which is the updated and improved versions of the normal TEC modules. These TEC modules can bear thermal cycling applications, thus the service life is longer than normal TEC modules.(more)
