Can metal film capacitors replace aluminum electrolytic capacitors? |Focus on mid-to-high-end brand capacitor manufacturers

Metal film capacitors replace all electrolytic capacitors. This topic has always existed since the birth of metal film capacitors. The main reason is the performance of aluminum electrolytic capacitors. Metal film capacitors can also do it. So some people have proposed metal film capacitors. Sooner or later, aluminum electrolytic capacitors will be replaced, but this sentence has been said for almost 20 or 30 years, only a small part of it has been realized, and most of them continue to use aluminum electrolytic capacitors. Why? Although metal film capacitors can replace all the performance of aluminum electrolytic capacitors, there is a big problem that the volume of metal film capacitors will increase with the increase in capacity. In this way, the installation of circuit boards will take up a lot of space and not too much. Reality, and the price will also become more and more expensive, so when this causes the need for large-capacity capacitors, aluminum electrolytic capacitors are still the first choice. Then there is the price issue just raised. In fact, the price difference is too big. If it is a small-capacity film capacitor, the price may not be much different. If it is a larger capacity, the price will double several times, and then these prices will finally It will still be displayed on the pricing of the product, so that its competitiveness in the market will decrease. Therefore, most manufacturers still prefer to buy aluminum electrolytic capacitors. Although they know that the performance of metal film capacitors is much better than that of aluminum electrolytic capacitors, the stability is much better. The service life is much better, but because of the price, there is no way to replace all metal film capacitors with aluminum electrolytic capacitors.
