3.3v voltage regulator circuit capacitor function Generally speaking, the input capacitor of the 3.3V voltage regulator chip is for filtering, and the capacitor is added at the output to prevent oscillation and degradation of voltage regulation performance. But this is really not so absolute. Now the chip design is getting better and better and the craftsmanship is getting better and better. Some chips can work even without adding capacitors, and you won't find the problem immediately. This...
1. Rectifier and filter circuit The task of the rectifier circuit is to use the unidirectional conductivity of the diode to convert the positive and negative alternating 50Hz grid voltage into a unidirectional pulsating DC voltage. The rectifier circuit only converts AC power into unidirectional pulsating voltage and current. Because the latter contains a large AC component, it is usually necessary to connect a filter circuit at the output of the rectifier circuit to filter out the AC component...

Reasons to purchase After Wusun returned last year, he found that the video part was still too small. In many environments, the video could be restored to the scene better and more realistically, but it was not shot. After many videos came back, it was still very unsatisfactory after powerful jitter elimination, and the quality of the video dropped badly. Eliminating jitter basically looked like I was going to vomit. All of us later understood the importance of holding a stabilizer. However,...
Gasket selection When any type of gasket is used, in order to ensure long-term effective sealing, the following eight important characteristics must be paid attention to when selecting and using the gasket: 1. Gas seal of gasket For the medium of the sealing system, the gasket can be used for a certain time within the appropriate temperature and pressure range without leakage. 2. Compressibility of gasket After the connection bolts are tightened, the contact surface of the gasket and flange...

How to choose and use sealing gaskets reasonably Medium, temperature, pressure and working conditions should be important factors. For example, when the working pressure is not high, use plastic flange butt (PN. Another example, in the working environment of chemical media, you must reasonably match different sealing media to achieve good results, otherwise unpredictable chemical changes are prone to occur. So any paradox in the choice of seals will lead to unimaginable consequences. The...
Around July last year, I started using the Zhiyun Smooth-II three-axis mobile stabilizer. At that time, I was still in contact with the stabilizer field for the first time. However, Zhiyun had not been so hot at the time and became the handheld device for numerous anchors and reporters. However, within a year's time, the old Smooth-II had a significant problem in stability. It was mainly an offset problem. Careful value-friends could be found in my original video. Smooth-Q, the successor of...
