History of Qihe Company

Author:Lucy Liang In 2005,we began to develop welding system solutions for surface mount component assembly (SMT) and through-hole insert process (THT).The development of our welding equipment has enabled us to have a deeper understanding of the manufacturing process in the field of electronic manufacturing, and our response ability has been greatly improved.However. It did not change […]

What protects the LED from over supplying of voltage?

Several circuit protection technologies – including metal-oxide varistors (MOVs), TVS diodes, LED protectors, and fuses – are needed to provide overvoltage, overcurrent, and high-temperature circuit protection for commercial LED lighting systems.To protect LEDs from too much current, you can use a current-limiting resistor in series with the LED.

SMD Power Supply Filter Design Tips

What is the purpose of using a filter in a circuit?A filter is a circuit capable of passing certain frequencies while attenuating (to reduce or block) other frequencies. Thus, a filter can extract important frequencies from signals that also contain undesirable or irrelevant frequencies. In the field of electronics, there are many practical applications for […]
