Electronic component

An electronic component (In search-chip you can find electronic components by searching the part number of the component) is any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form and are not to be confused with electrical elements, which are conceptual abstractions representing idealized electronic components.

Electronic components have a number of electrical terminals or leads. These leads connect to other electrical components, often over wire, to create an electronic circuit with a particular function (for example an amplifier, radio receiver, or oscillator). Basic electronic components may be packaged discretely, as arrays or networks of like components, or integrated inside of packages such as semiconductor integrated circuits, hybrid integrated circuits, or thick film devices. The following list of electronic components focuses on the discrete version of these components, treating such packages as components in their own right.


A capacitor (Electronic components) is a device that stores electrical energy in an electric field. It is a passive electronic component with two terminals. You will find capacitors in almost all electronic devices.

The physical form and construction of practical capacitors vary widely and many types of capacitor are in common use. Most capacitors contain at least two electrical conductors often in the form of metallic plates or surfaces separated by a dielectric medium. A conductor may be a foil, thin film, sintered bead of metal, or an electrolyte. The nonconducting dielectric acts to increase the capacitor's charge capacity. Materials commonly used as dielectrics include glass, ceramic, plastic film, paper, mica, air, and oxide layers. Capacitors are widely used as parts of electrical circuits in many common electrical devices. Unlike a resistor , an ideal capacitor does not dissipate energy, although real-life capacitors do dissipate a small amount. When an electric potential, a voltage, is applied across the terminals of a capacitor , for example when a capacitor is connected across a battery, an electric field develops across the dielectric, causing a net positive charge to collect on one plate and net negative charge to collect on the other plate. No current actually flows through the dielectric. However, there is a flow of charge through the source circuit.


A resistor (Electronic components) is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors (In search-chip you can find resistors by searching the part number of the component) are used to terminate transmission lines, to divide voltages, bias active elements, adjust signal levels, and reduce current flow, among other uses. High-power resistors (Electronic components) that can dissipate many watts of electrical power as heat, may be used as part of motor controls, in power distribution systems, or as test loads for generators. Variable resistors (Electronic components) can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical activity. Fixed resistors (Electronic components) have resistances that only change slightly with temperature, time or operating voltage.

Resistors (Electronic components) are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment like computers, cell phones, refrigerators, TVs, cars and more.
