Capacitance and energy stored in a capacitor can be calculated or determined from a graph of charge against potential.

Types of capacitors bitesize. Ceramic capacitors have a ceramic dielectric. You might be familiar with the small round disc like capacitors found on many pcbs. There are different types of capacitors available in the market.

Capacitance and energy stored in a capacitor can be calculated or determined from a graph of charge against potential. Single layer and multilayer. Virtually all types of capacitor are available as leaded versions.

These types of capacitors come in two main varieties. If two or more capacitors are connected in series the overall effect is that of a single equivalent capacitor having the sum total of the. Charge and discharge voltage and current graphs for capacitors.

Some of the common capacitor types are ceramic electrolytic which include aluminium capacitors tantalum capacitors and niobium capacitors plastic film paper and mica. When capacitors are connected in series the total capacitance is less than any one of the series capacitors individual capacitances. Series and parallel capacitors chapter 13 capacitors pdf version.

Charge and discharge voltage and current graphs for capacitors. Aluminum tantalum and niobium electrolytic capacitors are named after the material used as the anode and the construction of the cathode electrolyte. The key factor in distinguishing different types of capacitors is the dielectric used in its construction.

Film and paper capacitors are named for their dielectrics. Aluminum electrolytic capacitors aluminum capacitors are capacitors that are composed of two rolled up strips of aluminum foil with a strip of absorbent paper between them which is soaked in an electrolyte solution all this being sealed in a can. Some types of capacitors primarily tantalum and aluminum electrolytic capacitors as well as some film capacitors have a specified rating value for maximum ripple current.

Below is a list of the various types of capacitors as we go over the characteristics that make them up. Film capacitors are the most commonly available of all types of capacitors consisting of a relatively large family of capacitors with the difference being in their dielectric properties. These include polyester mylar polystyrene polypropylene polycarbonate metalised paper teflon etc.

Electrolytic ceramic supercapacitors plastic film silver mica glass and other specialist types. Ceramic caps along with electrolytic caps are the most widely available and popular capacitors. Capacitors are available as leaded varieties and surface mount capacitors.
