From telephones that allow us to communicate with individuals across the world to robust medical devices that save countless lives, electronics of all types have radically changed how our society functions as a whole. While numerous electronic devices and systems may vary in their functionality, application, and general appearance, almost all electronics will share many of the same basic components that serve as their building blocks. These common electronic part types can be classified into groups based on how they interact with energy, and the main three classifications include active, passive, and electromechanical components. Under each major category, a number of similar electronic part types may be found, each with their own unique characteristics and uses.
Active components are those that rely on a source of energy for their operation. Generally, many active components are those that can inject a circuit with power.
Semiconductors are a major type of active component, and they are materials designed to feature a resistance value that falls between that of a conductor and an insulator. Through doping and adjusting conductive properties, semiconductors can be made to have various characteristics to benefit different applications.
Transistors are a type of semiconductor device that are often used to either amplify or switch signals and power. As a basic building block for countless modern electronics, transistors feature three terminals that facilitate their attachment to external circuits.
Semiconductor diodes are the most common diode types, and they are crystalline semiconductor components that have a p-n junction attached to two electrical terminals. As the first semiconductors, such electronic part types may be used for regulating voltage, protecting circuits, tuning receivers, producing light, and more.
Integrated circuits are another popular electronic component related to semiconductors, and they consist of electronic circuits that have been placed on a semiconductor material such as silicon. With the implementation of a grand number of MOS transistors on a single chip, integrated circuits serve almost every modern electronic with their capabilities.
A display technology, or display device, is an electronic output device that is capable of providing information in a visual format. Often, such electronics will come in the form of television sets and computer monitors and will utilize an electrical signal to convey information.
Liquid-crystal displays (LCD) are a type of display technology, and such electronics utilize liquid crystals and polarizers to produce color or monochrome images with a backlight or reflector. LCD technologies can serve a variety of applications, often being used for televisions, computer monitors, aircraft cockpit displays, mobile phones, and more.
A cathode-ray tube (CRT) is a type of vacuum tube and display technology that may contain one or more electron guns. By altering the beams emitted by the electron guns, images can be generated and presented on a phosphorescent screen. With such electronics, oscilloscopes, television sets, computer monitors, radars, and other technologies may all benefit from CRT display capabilities. While CRTs have been in a steady decline after the release of newer technologies, CRT displays may still be found in a number of aircraft for instruments as they are cheap and easy to maintain.
A vacuum tube, electron tube, or valve, is an electronic part type that may control electric currents within a high vacuum when electric potential differences are applied to surrounding electrons. As key components of electronic circuits, vacuum tubes have assisted the development of the radio, television, radar, analog and digital computer, and other technologies. While vacuum tubes have mostly been superseded by semiconductor technologies, CRTs remain a popular type that serve aircraft cockpit instruments and other electronics.
Power sources are those that provide current to electronic circuits and devices, and they may come in a variety of forms to accommodate differing needs.
Batteries are one of the most common power sources, serving as portable storage devices that can change chemical energy into electrical energy to power mobile phones, laptops, flashlights, and even aircraft electronics.
Passive components are those that cannot introduce energy into a circuit and may not rely on any source of power besides the circuit they are attached to.
Resistors are one of the most widely used passive component types, and they are electrical components that reduce current flow, adjust signal levels, divide voltages, terminate transmission lines, and act as bias active elements for many electrical and electronic equipment.
Capacitors are devices that may store electrical energy within an electric field. As a Capacitor component that serves to add capacitance to a circuit, capacitors are regularly used within electronic circuits to impede the flow of direct current and facilitate alternating current.
Sensors are another popular passive electronic component, and they are used to detect events within an environment before relaying captured data to a connected electronic. While simple in their operation, sensors are crucial for the functionality of many electronics such as aircraft, automobiles, machinery, robotics, and more.
Electromechanical components are electronics that may use moving parts or electrical connections in order to conduct electrical operations.
Connectors are crucial for the operation of countless electronics, serving as devices that connect conductors to establish electrical circuits. Coming in many different configurations, connectors serve power, data, and audiovisual applications across many industries. While there are many methods of connection for connectors, common types include plug and socket, crimp-on, soldered, screw terminal, and blade connectors.
Switches are electric components that may be used to either disconnect or connect contacts to interrupt or divert current within a circuit. With a multitude of types available, switches can be operated or actuated through knobs, keyboard buttons, light switches, and other manual or automatic means.
Protection devices are often implemented within circuits and electrical equipment in order to protect sensitive components from excessive voltages or faults. Fuses are a popular one-time use protective device, and they are metal wires or strips that will melt and interrupt a circuit when a set current value is surpassed. As a sacrificial device, fuses can quickly stop the flow of current in the event of a short circuit or overload. Circuit breakers are another popular protection device, and they are electrical switches that will automatically disconnect when a fault is detected. Unlike fuses, circuit breakers may be reset after tripping and thus can be used multiple times.
