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.
