An electronic component is a basic Electronic element usually packaged in a discrete form with two or more connecting leads or metallic pads. Components are intended to be connected together, usually by Soldering to a Printed Circuit Board , to create an Electronic Circuit with a particular function (for example an Amplifier , Radio Receiver , or Oscillator ). Components may be packaged singly ( Resistor , Capacitor , Transistor , Diode etc) or in more or less complex groups as Integrated Circuit s ( Operational Amplifier , Resistor Array , Logic Gate etc). Very often electronic components are mechanically stabilized, improved in insulation properties and protected from environmental influence by being enclosed in Synthetic Resin Components may be Passive Or Active :
LIST OF ELECTRONIC COMPONENTS Many electronic components are on the market today. Here is a list of some of them. Wires and cables Devices to conduct electrical current Terminals and connectors Devices to make electrical connection
Cords Cables with connectors or terminals at their ends Switches Components that may be made to either conduct (closed) or not (open)
Resistors Components that dissipate electrical energy as heat. # See the Transducer section below for resistors used to sense environmental conditions (Thermistor, Photoresistor, RTD...) # See the Protection section below for resistors used for current or voltage limiting (MOV, Inrush Limiters...)
Protection devices Passive Components that protect circuits from excessive currents of voltages # While these components technically belong to the Wire, Resistor and Vacuum classes, they are grouped here based on their use. # Active components that perform a protection fuction are in the Semiconductor class, below.
Capacitors Components that store electrical charge in an electrical field
Magnetic (inductive) devices Electrical components that use magnetism
Networks Components that use more than one type of passive component
Piezoelectric devices, crystals, resonators Passive Components that use Piezoelectric effect
Power sources Sources of electrical power Transducers, sensors, detectors # Transducer s generate physical effects when driven by an electrical signal, or vice-versa. # Sensor s (detectors) are transducers that react to environmental conditions by changing their electrical properties or generating an electrical signal. # The Transducers listed here are single electronic components (as opposed to complete assemblies), and are Passive (see Semiconductors and Tubes for Active ones). Only the most common ones are listed here.
