Componentes

Electronic components are basic discrete devices in any electronic system to affect electrons or their associated fields. These components have two or more electrical terminals (or leads) aside from antennas which may only have one terminal. These components are usually industrial products, available in a singular form and are not to be confused with electrical elements, which are conceptual abstractions representing idealized electronic components and elements.

Types of Electronic Components

Electronic components are categorized into passive and active components.

• Active components depend on a source of energy (usually from the DC circuit) and can inject power into a circuit, though this is not part of the definition. Active components include transistors, integrated circuits, and some diodes like LEDs.
• Passive components can't introduce net energy into the circuit. They only rely on power that is available from the circuit. Examples include resistors, capacitors, inductors, and transformers.

Semiconductors

Semiconductors lie at the heart of modern electronics. They are materials which have a conductivity between conductors (generally metals) and nonconductors or insulators (such as most ceramics). Semiconductors are used to make devices such as diodes, transistors, and integrated circuits, which are the fundamental building blocks of today's electronic devices.

Identification and Classification

Electronic components are identified by a unique symbol and can be classified based on their packaging and the functions they perform. A detailed classification is as follows:

• Discrete components refer to those electronic components with just one circuit element, either passive or active, such as capacitors, resistors, or transistors.
• Integrated circuits or ICs are a set of electronic circuits on one small flat piece (or "chip") of semiconductor material, normally silicon. This integration helps to reduce the size and cost of the product and increase its reliability.

Applications

Electronic components are used in an exhaustive range of applications from simple circuits to complex devices like computers, mobile phones, and other consumer electronics. They are also essential in the fields of telecommunications, medical devices, and industrial machinery.

Manufacturing

The manufacturing of electronic components involves several processes including the design of the components, material selection, and assembly. Advanced manufacturing techniques such as lithography are used in the production of integrated circuits to place an enormous amount of electronic components on a small chip.

Environmental Impact

The production and disposal of electronic components have significant environmental impacts. Issues such as electronic waste (e-waste) and the use of hazardous materials in components necessitate proper recycling and disposal methods.

Future Trends

The future of electronic components lies in the development of smaller, faster, and more efficient devices. This includes advancements in nanotechnology and materials science which could lead to the creation of new types of components that are more energy-efficient and have a lower environmental impact.
