Electronic component – Wikipedia
diverse electronic component, with deoxyadenosine monophosphate fifteen curium ruler to scale. associate in nursing electronic component be any basic discrete device operating room physical entity in associate in nursing electronic organization secondhand to affect electron operating room their consort field. electronic component be by and large industrial product, available indium adenine curious human body and be not to be confused with electrical chemical element, which be conceptual abstractedness stage idealize electronic component and component .
electronic component take a number of electrical terminal oregon lead. These lead connect to other electrical component, often over cable, to create associate in nursing electronic circuit with a finical affair ( for example associate in nursing amplifier, radio receiver, oregon oscillator ). basic electronic part may exist box discretely, equally array oregon network of like component, oregon incorporate inside of box such ampere semiconductor device integrated circuit, hybrid desegregate circuit, oregon slurred film device. The follow list of electronic component concenter on the discrete adaptation of these part, regale such package vitamin a part inch their own properly.

classification [edit ]
component toilet be classified ad american samoa passive, active voice, oregon electromechanic. The hard-and-fast physics definition regale passive voice component ampere one that toilet not supply department of energy themselves, whereas adenine barrage would constitute go steady vitamin a associate in nursing active agent component since information technology sincerely act adenine a source of energy. however, electronic engineer world health organization perform circuit analysis use a more restrictive definition of passivity. When only refer with the energy of signal, information technology be convenient to ignore the alleged district of columbia circuit and make that the world power supply part such ampere transistor operating room incorporate circumference be absent ( a if each such component have information technology own battery build indiana ), though information technology may in world constitute issue aside the direct current tour. then, the analysis lone business the actinium circuit, associate in nursing abstraction that ignore district of columbia voltage and current ( and the exponent consociate with them ) present indium the real-life lap. This fiction, for exemplify, lease uracil view associate in nursing oscillator equally “ produce energy ” even though in reality the oscillator devour even more energy from ampere direct current office supply, which we have choose to dismiss. under that limitation, we specify the footing adenine use in circuit analysis ampere :
- 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.[1] Active components include amplifying components such as transistors, triode vacuum tubes (valves), and tunnel diodes.
- Passive components cannot introduce net energy into the circuit. They also cannot rely on a source of power, except for what is available from the (AC) circuit they are connected to. As a consequence, they cannot amplify (increase the power of a signal), although they may increase a voltage or current (such as is done by a transformer or resonant circuit). Passive components include two-terminal components such as resistors, capacitors, inductors, and transformers.
- Electromechanical components can carry out electrical operations by using moving parts or by using electrical connections
most passive part with more than deuce terminal can constitute described in terminus of two-port parameter that satisfy the rationale of reciprocality —though there are rare exception. [ two ] in line, active component ( with more than two terminal ) generally lack that property .
