Sound: The Evox-Rifa PHE 450 is a very transparent and clear sounding capacitor, some times a little too "fresh" sounding but this character can be compensated by adding a capacitor with a more round character – I had
Capacitors are essential in audio engineering. They maintain power during peak loads, smooth out noisy signals, and help create the sounds we love. In this article, we will explore what
Cyril''s capacitor article series in Electronics World, a few decades ago, were a landmark in our understanding of the mechanisms behind capacitor dielectric absorption and distortion. Now, Cyril updates this source of information taking into account both new insights and new wound and stacked capacitor products. The article contains numerous
Electolytic and tantalum capacitors have very poor audio characteristics and should not be used in the audio signal path. Replacing electrolytic capacitors in the audio signal path of your amplifier or preamp with film capacitors will improve sound quality.
When it comes to audio grade capacitors, the electrolytic capacitor (Amazon affiliate paid link) is the budget option. Compared to the film capacitor, the electrolytic cap is considered to be inferior, from the standpoint of sound quality. Some argue that if your loudspeaker is not super high-end, these types of caps are quite suitable and the
capacitors affect distortion in a real application. Figure 4. THD + N Variation with Non-ceramic Capacitors. Figure 5 shows the boards used for testing and Table 2 shows all of the capacitors included in this testing and their respective characteristics.

Capacitors discharge if their electrodes are connected to a conducting material. Lightening is an example of two electrodes – two charged layers of clouds, or a charged layer of clouds and the earth – that are separated by the dielectric air. We all know what it looks like when this particular capacitor discharges.
The Sound of Capacitors - Capacitor Linearity **Expanded** Many people believe there is a distinct sound to different types of capacitors. This article covers this topic by examining the linearity (or deviations from linearity) associated with different capacitor types. I''ve expanded this report and slightly re-arranged it to keep the load times reasonable. Background. A capacitor
The Sound of Capacitors - Capacitor Linearity **Expanded** Background. A capacitor is an energy storage device. The capacitance value is related to the size of the device plates, the spacing between them and the dielectric material of the media between the plates. In the simplest media (air or vacuum), the dielectric constant is unity. You can
Sound: The Evox-Rifa PHE 450 is a very transparent and clear sounding capacitor, some times a little too "fresh" sounding but this character can be compensated by adding a capacitor with a more round character – I had very good results with about 10% of the total value made up from Angela (Jensen) paper in oil. On its own I find the midrange
Ceramic capacitors are the most prevalent type of capacitor in electronics. They''re small, easy to work with, and extremely inexpensive. And, in theory, they do the same job as every other cap out there. Many players and
A film capacitor uses a thin film material to separate its charged plates and is typically a bit more expensive. They''re also longer-life, have better performance (in some cases) for audio, and may have higher temperature limits. Film capacitors are also offered in high voltage types which are great for vacuum tube audio designs. They''re
A capacitor – more commonly referred to as a ''cap'' around the traps – is a device that stores electrical charge, consisting of a pair of conductors separated by an insulator. The ratio of this stored charge to the voltage

Capacitors discharge if their electrodes are connected to a conducting material. Lightening is an example of two electrodes – two charged layers of clouds, or a charged layer of clouds and the earth – that are separated by the dielectric air.
A capacitor – more commonly referred to as a ''cap'' around the traps – is a device that stores electrical charge, consisting of a pair of conductors separated by an insulator. The ratio of this stored charge to the voltage between the conductors is a measure of the capacitance of the device.
When used in a car audio system, a capacitor can improve the sound quality by helping to keep the music signal clean. In order to get the most out of your car audio capacitor, it is important to know how to properly charge it. The first step is to make sure that your capacitor is rated for use in a car audio system. Next, connect the positive and negative terminals of the capacitor to the
Tantalum Capacitors: Known for their high capacity and small size, they can fail catastrophically if exposed to conditions beyond their specifications, such as reverse polarity or overvoltage. Ceramic Capacitors: While generally robust,
The Sound of Capacitors - Capacitor Linearity. Many people believe there is a distinct sound to different types of capacitors. This article covers this topic by examining the linearity (or deviations from linearity) associated with different capacitor types. Background. A capacitor is an energy storage device. The capacitance value is related
The capacitor is an open circuit for the DC voltage/current from the previous stage, but it allows the higher frequency AC signal to pass to the next stage. If you remove the entry capacitor to a new stage, the DC voltage from the
Caps are the bane of audio. I have an artical about passive components called "The Last Pass" that describes the down falls and your "best bets" in passives. Tantilum, mylar, polyester and electrolytics going from worse to better.
Audio grade capacitors are specifically optimized for high end audio applications, and offer higher performance in audio circuits than standard components. The types of capacitors that are commonly used in audio circuits
In audio amplification applications, capacitors couple the constant DC signals with the rapidly fluctuating voltages that drive speakers to help create a smooth sound. To create a bold and clean sound, larger capacitors work better than smaller ones. A large capacitance decreases the audio circuit''s impedance, limiting the amount of noise
I guess that sound isn''t necessarily for everyone, but it certainly is to my personal liking! Reading up on the available technical data, polypropylene makes a very good dielectric for film capacitors although capacitor ''sound'' is a highly contentious subject. However, as they say, ''I know what I like''! Regards, Felix.
Microscopic capacitors. These devices serve as data storage units in Flash memory. Considering the innumerable number of bits in Flash memory, microscopic capacitors contain the largest number of capacitors in use today. Capacitors in Series and Parallel. Capacitors, like resistors, can combine in parallel or series within a circuit. However
Electolytic and tantalum capacitors have very poor audio characteristics and should not be used in the audio signal path. Replacing electrolytic capacitors in the audio
When it comes to utilizing capacitors in audio applications, the sky is the limit. Creating unique sounds hinges on the fundamental principles that define capacitor technology, and exploring the variations in these principles can lead to a robust understanding of audio engineering. Audio-grade capacitors have a noticeable impact on sound quality.
Some dielectrics materials are piezoelectric and the noise they add to a capacitor manifests itself as a small battery inside a component. In addition, electrolytic capacitors have parasitic diodes that can cause changes to bias or signal characteristics.
For instance, if the bass level in a particular song increases very quickly, there may not be enough voltage available to power the speaker to the levels indicated by the audio signal. In such cases, capacitors can help out in the short term by lending their charged energy. This is known as “evening out“ the voltage.
How capacitors make modern audio engineering possible Capacitors feature prominently in the world of audio engineering. These unassuming-looking components have the ability to smooth out noisy signals, maintain power during peak loads, and help create the sounds we know and love. Audio-grade capacitors span a variety of applications.
Capacitors DO make an audible difference ! Electolytic and tantalum capacitors have very poor audio characteristics and should not be used in the audio signal path. Replacing electrolytic capacitors in the audio signal path of your amplifier or preamp with film capacitors will improve sound quality.
