TEC modules (thermal electric cooler), also called Peltier modules, can cool down or heat up the object when changing the current direction. The current is DC current. There are some advantages and disadvantages of TEC module. Advantages: A. No cryogen needed. TEC modules can work constantly for hours. It contains no pollution or rotating components, which results no noise and vibration, long life span and easy installation. B. Very short heating-up and cooling time due to small thermal lag in T...(more)
LED lamp usually contains a LED array. According to the preset program, LED controller can control the switch at each position in the LED lamp circuit and lighten LED regularly to show a specific text or graphics. LED lamps connect together in series, and they should be driven by a constant power supply. When using, the current control needs to be strict in order to ensure the LED lamp work normally for the brightness of each LED is determined by current. The pictures of LED lamp and LED control...(more)
SMT capacitors are famous for high stability, reliability and precision in IC design and have been widely used in many electronic fields. Chip capacitor can eliminate high frequency interference produced by itself, so that other chip modules will work well without any interference. In high frequency electronic oscillation circuit, chip capacitors and crystal oscillator form a oscillation circuit, which provides clock frequency for various circuits. Chip capacitor has different sizes, 0402,0603,0...(more)
SMT inductor is also called power inductor or high current inductor. The SMT inductor can be divided into two types: one is with magnetic cover, the other one without magnetic cover. In a circuit, SMT inductor mainly has the functions of filter and oscillation.The inductor has the advantages of miniaturization, high quality, high energy storage and low resistance. Therefore, our company (ATI) has designed and manufactured SMT inductor kits to storage the inductors as in the following picture. An...(more)
LED driver is an electronic device, which is used for driving LED to light or LED modules to work normally. Due to conduction characteristics of LED PN junction, the LED driver can only adapt to a narrow variable range of the supply voltage and current. If the range changes a little, it will lead that LED may not be light up, the luminous efficiency will reduce seriously, the LEDs service lifetime can be shorten, or even the chip can be damaged. A fundamental frequency power supply and common ba...(more)

Resistor kits SMD resistor, 1% precision, resistance range of 0~20M; Packaging forms: 1026, 0805, 0603, 0402; Each small box cover has the corresponding resistance valu...(more)
The incentive method of laser drivers is mostly injection current form. When the injection current is greater than the threshold current, radiation power will rapidly rise with the increase of the current. Therefore, by changing the injection current, the output optical power can be adjusted. In order to control semiconductor laser, the methods of automatic control are usually adopted, which includes constant current/power/voltage control. In the constant power control mode, by using photoelectr...(more)
