Relays
Relays are electrically operated switches. Many relays use an electromagnet to operate a switching mechanism mechanically, but other operating principles are also used. Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal. Several common types include latching relays, reed relays, mercury-wetted relays, polarized relays, machine tool relays, ratchet relays, contactor relays, solid-state relays, solid state contactor relays, Buchholz relays, Forced-guided contacts relays and overload protection relays.
Integrated Circuits (ICs)
Integrated circuits are also referred to as ICs, chips, or microchips. The integration of large numbers of tiny transistors into a small chip replaces the manual assembly of circuits using discrete electronic components. Integrated circuits has many features such as mass production capability, reliability, and building-block approach to circuit design, which makes the adoption of standardized ICs in place of designs using discrete transistors. Compared to discrete circuits, integrated circuits have the advantages of low cost and high performance. Integrated circuits can be classified into analog, digital and mixed signal (both analog and digital on the same chip). The manufacturing process includes fabrication, packaging and chip labeling and manufacture date. They are widely used in all electronic equipment today, including computers, mobile phones, and other digital appliances.
Connectors
Connectors are electro-mechanical devices for joining electrical circuits as an interface using a mechanical assembly. They may join two lengths of flexible copper wire or cable, or connect a wire or cable or optical interface to an electrical terminal. The connectors are characterised by the pinout and physical construction, size, contact resistance, insulation between pins, ruggedness and resistance to vibration, resistance to entry of water or other contaminants, resistance to pressure, reliability, lifetime (number of connect/disconnect operations before failure), and ease of connecting and disconnecting. The types of connectors include terminal block, insulation displacement connector, plug and socket connector, component and device connector, etc. The most used connectors cover 8P8C connectors, USB connectors, power connectors and DC connectors.
Capacitors
Capacitors (formerly known as condensers) are passive two-terminal electrical components used to store energy in an electric field. All the capacitors at least include two electrical conductors separated by a dielectric (insulator). There are several different types of capacitors due to the dielectric materials. The common types include ceramic capacitors, supercapacitors, glass and mica capacitors, electrolytic capacitors. Capacitors are widely used in electronic and electrical systems. The typical applications include energy storage, pulsed power and weapons, power conditioning, supression and coupling, motor starters, signal processing and sensing.
Resistors
Resistors are common elements of electrical networks and electronic circuits and are common in most electronic equipment. Practical resistors can be made of various compounds and films, as well as resistance wire (wire made of a high-resistivity alloy, such as nickel-chrome). Resistors are also implemented within integrated circuits, particularly analog devices, and can also be integrated into hybrid and printed circuits. The electrical functionality of a resistor is specified by its resistance: common commercial resistors are manufactured over a range of more than nine orders of magnitude. Practical resistors are also specified as having a maximum power rating which must exceed the anticipated power dissipation of that resistor in a particular circuit: this is mainly of concern in power electronics applications. Practical resistors have a series inductance and a small parallel capacitance; these specifications can be important in high-frequency applications.
Discrete Semiconductor Products
Discrete semiconductor products are electronic components with just one circuit element, either passive (resistor, capacitor, inductor) or active (transistor or vacuum tube), other than integrated circuits. Several discrete semiconductor devices are combined to form a discrete circuit. Such discrete circuits are different from integrated circuits and hybrid circuits, which are built from several circuit elements in one package. The typical discrete semiconductor products include transistors, diodes, TRIACs, LED.
Switches
Switches are electrical components that can break an electrical circuit, interrupting the current or diverting it from one conductor to another. A switch may be directly manipulated by a human as a control signal to a system, such as a computer keyboard button, or to control power flow in a circuit, such as a light switch. Automatically operated switches can be used to control the motions of machines, for example, to indicate that a garage door has reached its full open position or that a machine tool is in a position to accept another workpiece. Switches may be operated by process variables such as pressure, temperature, flow, current, voltage, and force, acting as sensors in a process and used to automatically control a system. For example, a thermostat is a temperature-operated switch used to control a heating process.
Circuit Protection
Circuit Protection devices are used to protect wires and connectors from being damaged by excess current flow caused by an over current or short-circuit. Excess current caused excess heat, which causes circuit protection to “open circuit”. Fuses, fuse elements, fusible links and circuit breakers are used as circuit protection devices. Circuit protection devices are available in a variety of types, shapes and specific current ratings.
Sensors, Transducers
Sensors are devices that measure a physical quantity and converts it into a signal which can be read by an observer or by an instrument. The sensors receive and respond to a signal. The sensitvity indicate how much the sensors’ output changes when the measured quantity changes. Sensors are used in everyday objects such as touch-sensitive elevator buttons (tactile sensor) and lamps which dim or brighten by touching the base. There are also innumerable applications for sensors of which most people are never aware. Applications include cars, machines, aerospace, medicine, manufacturing and robotics. Transducers are devices that convert one type of energy to another. Energy types include (but are not limited to) electrical, mechanical, electromagnetic (including light), chemical, acoustic or thermal energy. For the term transducers commonly implies the use of sensors/detectors, any devices which convert energy can be considered transducers. Transducers are widely used in measuring instruments.
Inductors, Coils, Chokes
Inductors (or reactors or coils) are passive two-terminal electrical components used to store energy in a magnetic field. The ability of inductors to store magnetic energy is measured by inductance, in units of henries. Inductors are one of the basic components used in electronics where current and voltage change with time, due to the ability of inductors to delay and reshape alternating currents. Inductors called chokes are used as parts of filters in power supplies or can be used to block AC signals from passing through a circuit.
Optoelectronics
Optoelectronics are electronic devices that source, detect and control light, usually considered a sub-field of photonics. Optoelectronic devices are electrical-to-optical or optical-to-electrical transducers, or instruments that use such devices in their operation. Optoelectronics usually include display modules, fiber optics, lamps, LEDs , laser diodes, infrared emitters, and LED thermal products.
Power Supplies
Power supplies are devices that supply electrical energy to one or more electric loads. They can obtain energy from electrical energy transmission systems, energy storage devices, electromechanical systems and solar power. Every power supply must obtain the energy it supplies to its load, as well as any energy it consumes while performing that task, from an energy source. Common power supplies types include battery, DC power supply, AC power supply, linear regulated power supply, AC/DC supply, switched-mode power supply, programmable power supply, uninterruptible power supply, high-voltage power supply and voltage multipliers. Power supplies are widely used in computer power supply, welding power supply and AC adapter.
RF and RFID
RF (Radio frequency) is a rate of oscillation in the range of about 3 kHz to 300 GHz, which corresponds to the frequency of radio waves, and the alternating currents which carry radio signals. RF usually refers to electrical rather than mechanical oscillations, although mechanical RF systems do exist (see mechanical filter and RF MEMS). Radio-frequency identification (RFID) is a technology that uses radio waves to transfer data from an electronic tag, called RFID tag or label, attached to an object, through a reader for the purpose of identifying and tracking the object. Some RFID tags can be read from several meters away and beyond the line of sight of the reader. The application of bulk reading enables an almost-parallel reading of tags. The RFID tag includes a small RF transmitter and receiver. An RFID reader transmits an encoded radio signal to interrogate the tag. The tag receives the message and responds with its identification information. The RFID system design includes a method of discriminating several tags that might be within the range of the RFID reader. RFID can be used in many applications. A tag can be affixed to any object and used to track and manage inventory, assets, people, etc.
