How much do you know about the detailed structure of metal film capacitors|Focus on mid-to-high-end brand capacitor manufacturers

Metal film capacitors can be divided into many types according to different media, such as electrolytic capacitors, paper capacitors, ceramic capacitors, mica capacitors, film capacitors, air capacitors, and so on. The most frequently used in audio equipment are electrolytic capacitors and metal film capacitors. Electrolytic capacitors are usually used in places where power consumption is relatively large, such as the use of the main power source, because in addition to filtering, they can also save power, and metal film capacitors are often used in simulations. The signal connection, or the bypass of the power supply noise, uses the anti-crossing method, which is mainly used in these places. At the same time, the structural advantages of metal film capacitors: First, the main circuit inside the core adopts a copper strip bridging process structure, the thickness of the copper strip is guaranteed, the main circuit has a strong flow capacity, and the temperature rise of the copper strip is low. The installation and operation are simple, convenient, fast and efficient, which greatly reduces the probability of error. Second, the main circuit of the metal film capacitor only needs two copper strips, instead of a large PCB in the past. The cost of product materials and labor costs are greatly reduced, and product reliability is improved. Eliminates the need for PCB plug-in, tin furnace, repair soldering and other processes. Third, the main circuit is separated from the drive control part, so that the strong current/weak current can be separated. Reduce the interference of the main resonant circuit to the drive part of the chip. It brings convenience to the after-sales maintenance of the product, the components can be reused, and the maintenance cost is reduced. Fourth, since the capacitors are all packaged in module form, the aluminum shell can be used to dissipate heat, and the movement can be completely sealed. Solve the problem of oil fume, moisture, cockroaches, metal dust, etc. entering the inside of the movement, and improve the reliability and service life of the product. Fifth, the gold film capacitor is changed from multiple discrete parallel to a single module form, which solves the problems of uneven overcurrent and uneven partial voltage of discrete capacitors, shortens the line distance of the main circuit, and reduces the line distribution inductance. The impact on power components.

At a time when technology is essential for electrolytic capacitor, ensuring that it works in a symbiotic way with your human employees is key.
