Active components include amplifying components such as transistors, triode vacuum tubes (valves), and tunnel diodes. Active components rely on a source of energy (usually from the DC circuit, which we have chosen to ignore) and usually can inject power into a circuit, though this is not part of the definition.Under that restriction, we define the terms as used in circuit analysis as: This fiction, for instance, lets us view an oscillator as 'producing energy' even though in reality the oscillator consumes even more energy from a DC power supply, which we have chosen to ignore. Then, the analysis only concerns the AC circuit, an abstraction that ignores DC voltages and currents (and the power associated with them) present in the real-life circuit. When only concerned with the energy of signals, it is convenient to ignore the so-called DC circuit and pretend that the power supplying components such as transistors or integrated circuits is absent (as if each such component had its own battery built in), though it may in reality be supplied by the DC circuit. However, electronic engineers who perform circuit analysis use a more restrictive definition of passivity. The strict physics definition treats passive components as ones that cannot supply energy themselves, whereas a battery would be seen as an active component since it truly acts as a source of energy. The following list of electronic components focuses on the discrete version of these components, treating such packages as components in their own right.Ĭomponents can be classified as passive, active, or electromechanic. Basic electronic components may be packaged discretely, as arrays or networks of like components, or integrated inside of packages such as semiconductorintegrated circuits, hybrid integrated circuits, or thick film devices. These leads connect to create an electronic circuit with a particular function (for example an amplifier, radio receiver, or oscillator). 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.Įlectronic components have a number of electrical terminals or leads. An electronic component is any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields.
