NTC is short for Negative Temperate Coefficient. Resistance is varied with the temperature change, and its resistance will decrease when the temperature rise and vice-versa. For example, the resistance is 50kΩ when it is at 25℃, while the resistanc...(more)
This dual mode laser diode driver LDA1-CP1 is designed for driving P type laser diode. This laser driver can control and monitor the output driving current and output laser power. The laser driver comes with PWM output stage with an efficiency of over 90%, so it doesnt need any heat sinks. For this laser driver, the output current and laser power can be set by two independent input voltages linearly, and can also be monitored by its output voltages respectively. This laser driver has a 2.5V low...(more)
ATE1-TC-199 long life TEC modules have 199 pairs of Peltier elements, and no moving parts. Long life refers that these TEC modules have a long service life when suffering frequent changes between heating and cooling. Standard TEC modules will have a shorter life time when suffering the same. Many experiments show that ATE1-TC-199 TEC modules have significantly long life time in thermal cycling applications. The maximum input voltage is 27.4V, and the current is 13A. There are two types in this s...(more)
ATE1-TC-127 series TEC modules come with 127 pairs of Peltier elements, with the maximum input voltage of 17.5V or 16.2V. These TEC modules can be used in thermal cycling applications with a long service life. There are currently six models in this series, and the current can be 5.5A, 5.7A,7.8A, 8A and 12.1A. Therefore, the power ratings are different. The maximum temperature that this series TEC modules can attain can be 74.5C, 72.5C and 72C. There are two sealing version available, sealed and...(more)
Long life TEC modules refer to those that are designed for thermal cycling applications, i.e. frequent changes between heating up and cooling down. It is not practical for standard TEC modules since the life time will be largely reduced. This long life TEC module has much longer operational life than standard TEC in terms of thermal cycling application, thus it can be also called thermal cycling TEC module. This thermal cycling TEC module comes with a maximum input voltage of 9V. There are two m...(more)
TEC module is also called thermoelectric cooler that is used to cool down or heat up objects. Long life TEC modules refer to those TECs that can be used in thermal cycling application, such as PCR devices, thermal cyclers, chillers and analyzers, thus they are also called thermal cycling TEC modules. The ATE1-TC-70-15AS TEC module comes with 70 pairs of Peltier elements and a maximum input voltage of 9.6V. The maximum current of this TEC module is 15A. The maximum temperature difference that thi...(more)
SMD inductors, resistors and capacitors are widely used in electronic products nowadays due to the stable performance and small sizes. This article introduces a inductor container that stores SMD inductors of different sizes and values. The container is an enclosure with more than 100 lidded compartments inside and a final top cover that can close the whole enclosure, as shown in the picture below. Moreover, there is a foam pad inside the top cover, which is used to keep all the lids of the comp...(more)
ATLSXA202D series laser diode drivers are designed to drive laser diodes with high efficiency, more than 90%. This laser diode driver can output constant current and there are multiple options for the maximum output current, 500mA, 1A, 2A, 3A, 4A or 6A. This laser diode drive feature frequency synchronization function, which allows the laser driver using an external digital signal (within the range from 520kHz to 800kHz) to synchronize the internal PWM output stage of this laser driver, thus eli...(more)
