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 […]

General Knowledge of PCB OSP Surface Finish

Copper plays a conductive role in printed circuit boards (PCBs). As a reactive chemical, copper is prone to oxidation when exposed to atmospheric humidity, thereafter leading to problems that may occur in high-temperature soldering, which is detrimental to the reliability of the components mounted on the PCB and the final product.

Wireless communication technology – an overview

Wireless communication technology essentially uses wireless transmission media to achieve interconnection and interoperability between terminals. This wireless medium can be electromagnetic waves or light waves. In fact, according to the theory of quantum mechanics, light waves are also a kind of electromagnetic waves. The difference between them is The wavelengths are different. Today qihe smt pick and place machine sharing A brief summary of wireless communication technology
