FAQ
Â
1.Is this optocoupler a high-speed optocoupler?
ot a high-speed optocoupler, this is an ordinary triode optocoupler.Used in switching power supply, programmable controller, household appliances, office equipment and other products.
Â
2.217 Optocouplings are generally used in what fields?
217 optocouplings are generally used in digital circuits, such as feedback output voltage, primary and secondary communication. Optocoupler is a device that transmits electrical signals through light as the medium. It has the advantages of small size, long life, no contact, strong anti-interference ability and so on.
Â
3.How about domestic optocoupler performance, quality stability?
The performance and quality of domestic optocouplings have been continuously improved and recognized. Fujian Tiandian Optoelectronics Co., Ltd. has successfully developed and mass-produced multiple series of optocouplers, and is widely used in smart home, mobile Internet, intelligent instruments, intelligent vehicles, medical equipment, industrial control, consumer and industrial products. In addition, optocoupler can be used in communication equipment for signal isolation, photoelectric conversion and other functions, and is usually used in the computer field to isolate the electrical connection between the computer and external devices. Therefore, the domestic optocoupler has been able to meet the needs of various applications in terms of performance, and the quality is relatively stable and reliable.
Â
4.What are the domestic optocoupler manufacturers?
There are many domestic optocoupler manufacturers, among which the more well-known companies include Tiandian Optoelectronics, Olund, Qunxin Micro, Dapeng, Kuangtong and other companies.
Â
5.What is the difference between white optocoupler and black optocoupler?
The main difference between a white optocoupler and a black optocoupler is the color of the shell. Optocoupler is a circuit module that completely isolates the input and output, which is often used in the design of digital circuits with strong anti-interference ability and stable operation. There is no difference between the white optocoupler and the black optocoupler in the internal structure, and the input end is connected with an infrared light-emitting diode, and the output end is connected with a light detector. In practice, white and black optocouplings can be used interchangeably.
