Capacitors insertion reverse can be detected by image recognition or ICT For capacitors with polarity, such as electrolytic capacitors, tantalum capacitors, etc., it is absolutely not allowed to plug them in reverse. If they are plugged in reverse, they will soon fail or even burst. In the production of circuit boards, it is very necessary to [...]
A single-phase motor with a slightly larger power is generally equipped with two capacitors, namely the starting capacitors and the running capacitor. Before 70 years, single-phase motors were mostly a capacitor, which is a starting capacitors. After the motor is started, the capacitor is thrown off by the centrifugal switch, and only the main winding works [...]
A parallel plate capacitor is composed of two parallel metal conductor plates, separated by a dielectric material in the middle. When there is a certain potential difference between the two plates, there will be an electrostatic field distribution between the plates. There is a uniform electric field distribution in the part between the two plates. Due [...]
We know that a series of AC coupling capacitors in the series signal can provide DC bias and overcurrent protection, but this will also bring another problem to the link PDJ (Pattern-Dependent Jitter). The placement of AC coupling capacitors has just been solved, and now we have encountered the value selection problem! Obviously, the AC coupling [...]
The Olympics is approaching, Tokyo's security will be raised to the largest scale. The opening of the Tokyo Olympics is just around the corner, and local security work is being promoted intensely. During the Tokyo Olympics and Paralympics, all parts of Japan will send support police forces to Tokyo, and about 60,000 people will be [...]
