An excellent speaker system is distinguished not only by the fact that it reproduces clear and loud sound, but also by the fact that these sounds can spread throughout the entire area. To experience the entire sector of the reproduced sound and increase the power by an order of magnitude, music lovers use life hacks. A capacitor is a clever assistant device for this purpose. A very small device whose purpose is to store the required amount of energy. What is its operating principle? Installed on the sound card, it conducts current, filters the load, and helps play sound.
Now there is a wide variety of models on the market that differ in price, power level and technical features. To choose the best option, you need to have a good understanding of what types there are, what their advantages are and what sound cards they are suitable for. To know exactly which capacitors are worthy of purchase, the site’s editors compiled the top 2022 using reviews from real users, technical specifications and comparative analysis of the most popular models.
Varieties used in modern sound cards
A few categories to consider for energy storage devices used in amplifiers are:
- electrolyte based;
- based on different types of film;
- paper based.
All such subspecies are used to create a sound wave. If you don’t have experience, it’s difficult to understand the differences between the different types of parts presented on the modern market; everything seems approximately the same; in fact, a correctly selected capacitor affects not only the quality, but also largely the ease of use of the sound card.
Electrolytic
When the main role of the dielectric is an oxide at the base of the metal (foil), and an electrolyte at the cathode, such devices are called electrolytic. Such models have a fairly large capacity and a long service life - various versions of such a product allow you to work from 3 to a maximum value of 8 thousand hours at the highest temperature conditions. The advantage of this type of device is its relatively good reliability and low price. The downside is that to develop reliable Hi-Fi equipment on it, you need to put in a lot of effort.
Devices of this type are very mediocre for sound, since the long charging process and the slow discharging process (all due to ionic processes) interfere with high-quality sound reproduction. In practice, breakdowns occur quite often, due to which not only the sound card, but also other equipment can fail, although in theory such devices have a high barrier to wear. They are used in inexpensive models to reduce the overall price of the finished product, as this is economically beneficial for manufacturers. As for the consumer, such a choice is detrimental to him. The low price, unfortunately, in this case does not come with the high quality in the pen as a music lover would like.
Of course, there are a small number of copies that produce not bad results, and this fact could cause joy if not for one unpleasant moment. Such models were often installed in limited editions; finding such an example is sometimes not easy.
Film
When a film (fluoroplastic, polyethylene, polystyrene, etc.) is used as a substance that poorly conducts current, this type is called film. The type in question is characterized by increased insulation resistance. A distinctive feature is the ability to self-heal after dielectric breakdown. The temperature for normal operation should not exceed 200 degrees.
Compared to electrolytic films, they lose in capacity, but gain in speed of work. Film models act as a voltage filter, plus the separation-transition responsibilities are assigned to them. This improves the sound quality many times over. Although the price of film ones is an order of magnitude higher than electrolytic ones, they cope with the main task much better.
For each individual device model, such devices are selected purely individually. The use of film options greatly influences decisions in the manufacture of sound cards. The problem arises due to low power; they either have to be combined with electrolytic ones or use other design approaches.
When several types of capacitors are combined in pairs, most of them are of the film type, and a smaller part are of the electrolytic type. Thanks to this, electrolytic ones do not significantly distort the sound, but they help in more rational use of energy.
Paper
The next type of energy-storing devices that are successfully used in audio equipment is paper. Such products use parts that include paper; it can be either dry or impregnated with a special substance. This is the highest quality and highest priced type of product. Despite the fact that they are combined in use with electrolytic paper ones, they retain the highest sound quality and retain excellent performance. Of course, it is no secret that knowledgeable music lovers are able to distinguish the sound of paper devices from all other types.
There are paper-film versions, and there are only paper versions. The considered option is often installed according to a special order from the client, so we can say that this is a piece product.
