There are a lot of different capacitor types, all with their own applications, characteristics and construction. This page lists the different capacitor types which are described on the capacitor guide. Air capacitors use air as a dielectric. Simplest air capacitors are made up of two conductive plates separated by an air gap.
Capacitors are divided into two mechanical groups: Fixed-capacitance devices with a constant capacitance and variable capacitors. Variable capacitors are made as trimmers, that are typically adjusted only during circuit calibration, and as a device tunable during operation of the electronic instrument. The most common group is the fixed capacitors.
Ceramic capacitors, especially the multilayer style (MLCC), are the most manufactured and used capacitors in electronics. MLCC is made up of alternating layers of the metal electrode and ceramic as the dielectric. And due to this type of construction, the resulting capacitor consists of many small capacitors connected in a parallel connection.
Standard, bi-polar, and polymer types are included. Figure 5: An illustration of the range of voltage/capacitance ratings for aluminum capacitors available through DigiKey at the time of writing. The primary strength of aluminum capacitors is their ability to provide a large capacitance value in a small package, and do so for a relatively low cost.
Epoxy Case (Rectangular & Round) – where the capacitor is encased in a moulded plastic shell which is then filled with epoxy. Metal Hermetically Sealed (Rectangular & Round) – where the capacitor is encased in a metal tube or can and again sealed with epoxy. with all the above case styles available in both Axial and Radial Leads.
According to the number of values per decade, these were called the E3, E6, E12, E24 etc. series. The range of units used to specify capacitor values has expanded to include everything from pico- (pF), nano- (nF) and microfarad (μF) to farad (F). Millifarad and kilofarad are uncommon.
Film capacitors also come in an assortment of shapes and case styles which include: Wrap & Fill (Oval & Round) – where the capacitor is wrapped in a tight plastic tape and have the ends filled with epoxy to seal them. Epoxy Case (Rectangular & Round) – where the capacitor is encased in a moulded plastic shell which is then filled with epoxy.

Capacitors are used in various electronic circuits and devices. Based on the application there are different types of capacitors available in the market. Hence, it becomes necessary to learn about each type before selecting one. In this article, we will discuss the most popular types and their practical applications. How are capacitors classified?
The types of capacitor available range from very small delicate trimming capacitors using in oscillator or radio circuits, up to large power metal-can type capacitors used in high voltage power correction and smoothing circuits.

Variable capacitors are made as trimmers, that are typically adjusted only during circuit calibration, and as a device tunable during operation of the electronic instrument. The most common group is the fixed capacitors.
The working voltage of the capacitor depends on the type of dielectric material being used and its thickness. The DC working voltage of a capacitor is just that, the maximum DC voltage and NOT the maximum AC voltage as a capacitor with a DC voltage rating of 100 volts DC cannot be safely subjected to an alternating voltage of 100 volts. Since ...
Three distinct types are available; the standard aluminum electrolytic capacitor, a bipolar variant on that theme, and a newer type which incorporates a conductive polymer electrode. Referring to the family as "aluminum capacitors" rather than "aluminum electrolytic capacitors" is a hat-tip to this latter device type which doesn''t ...
Another popular type of capacitor is an electrolytic capacitor. It consists of an oxidized metal in a conducting paste. The main advantage of an electrolytic capacitor is its high capacitance relative to other common types of capacitors. For example, capacitance of one type of aluminum electrolytic capacitor can be as high as 1.0 F. However, you must be careful …
Here the paper is placed between two aluminum metal foils and is rolled into a cylindrical shape. Two lead wires are connected to metal foils for external connection. The whole unit is dipped in wax and placed in a metal …
You''ll find one or more capacitors in almost every electronic circuit you build. And capacitors come in all sorts of shapes and sizes, influenced mostly by three things: the type of material used to create the plates, the type of material used for the dielectric, and the capacitance.
Variable Capacitor Types. Variable capacitors are distinguished by the fact that their capacitance can be changed. Basically, there are two most common types of such capacitors: trimmer and rotor-stator capacitors. Rotor-Stator Capacitor. The rotor-stator type of capacitor comprises two metallic plate sets. The moving plates are attached ...
Polar capacitors are further classified into two types: 1.1.1. Electrolytic Capacitors 1.1.2. Supercapacitors. 1.1.1) Electrolytic Capacitors: An electrolytic capacitor is a type of polar capacitor that uses an electrolyte as one of its electrodes to maintain heavy charge storage.
In this post, you''ll learn what is a capacitor. Its definition, diagram, working, specifications, applications, capacitance color coding, and types of capacitors with pictures. You can also download the PDF file of this article at the end. What is a Capacitor? Capacitors an electrical or electronic component that stores electric charges.
The most commonly available of all types of capacitors are the film capacitors which consist of a relatively large family of capacitors with the difference being in their dielectric properties. They can come in an assortment of shapes and case styles including wrap & fill (oval & round), epoxy case (rectangular & round) and metal hermetically ...
The physical size and shape (cylindrical, disc, rectangular) can also give clues about its type. In some cases, color coding or additional alphanumeric codes might be used to provide further details. What is COG or …

This type of capacitor is another subtype of the electrolytic capacitor. They are made of tantalum metal that acts as an anode, covered by a layer of oxide that acts as the dielectric, surrounded by conductive cathode. Tantalum allows for a very thin dielectric layer resulting in a higher capacitance value per volume, superior frequency characteristics compared to other types of …
Capacitor Types - Introduction Capacitors come in a variety of shapes and sizes, but what most people don''t realize is that they also have different effects and purposes.
