Audio grade capacitor types. Before we talk about which are the best audiophile capacitors, let''s talk about what a capacitor is in the first place. A capacitor is one of the 3 passive electrical components : resistors, capacitors and inductors. A capacitor is basically a frequency dependant resistor.

I remember tearing capacitors apart as a child in the 70''s (and trying to launch old dead valves as "rockets") and the caps all used aluminium foil rolls and some kind of grease. Only the variable caps used solid metal plates. I never tore a cap apart later on, but certainly have had my fair share of exploding electrolytics!

Both of the non-ceramic types will hold their capacitive value under use condition, unlike ceramics.... Ceramic capacitors are generally not recommended for use as AC coupling in audio. They are attractive because of the size, cost and low ESR. However, when most ceramic capacitors are biased, the capacitive rating can decrease by as much as 50%!

Capacitor values are given in farad (F), usually in microfarad (µF) and volts (V). The farad value indicates what is known as a capacitor''s capacitance rating, or simply capacitance, which tells us how much energy a capacitor contains at a given voltage. A capacitor with a 1 farad capacity, can be charged with 1 volt.

type capacitors. These capacitors store energy along alternating plates separated by a dielectric film. Charge is stored statically along the lengths of the plates. The basic configuration of the film capacitor is provided in Figure 1. The capacitance itself is controlled by the area and relative separation of the plates.

The equivalent circuit for a capacitor is generally modeled as a simple series RLC circuit, which gives a minimum in the impedance curve for the capacitor. When we are operating above the typical digital range of off-the-shelf capacitors that would be used in digital systems, we also have to consider the parasitics of the pads and nearby reference planes.

Class II ceramic capacitors include X5R and X7R, which have a higher temperature coefficient. X5R capacitors have the lowest temperature rating, but offer the lowest cost.
Polyester film capacitors are the best type of capacitors when you need high stability, and/or low source impedance. They are usually relatively expensive in comparison to other dielectric materials. Also, they have a low dielectric constant meaning their capacitance is low for its size.
A capacitor is made up of two conductive plates, which are separated by an insulating material called a dielectric. The plates are usually made out of materials like aluminium and copper, and the dielectric can be made out of materials like ceramic, plastic and paper. Capacitors can range in voltage, size and farads (F) of capacitance.
Aluminium is particularly suited for robust capacitor designs, as it is very little affected by atmosphere as compared to zinc. Aluminium metallization layer, when stored in air, gets oxidized on surface, forming extremely thin Al 2 O 3, which protects the inner volume of metal layer.
What are different types of metallization used in capacitor films? Metallized capacitor films have a thin coating of metal (commonly aluminium and zinc) deposited on them by vacuum deposition process. Several types and patterns are available to choose for metallization, depending on application and usage environment.
Ceramic capacitors are known to maintain stability over a wide range of temperatures and can be used as general-purpose capacitors but are used in decoupling, bypass, filtering, RF, and timing circuits. Their size and low-cost lead them to be the primary choice for dielectric material until their limitations are reached. Pros Cons
