Electronic components are components that make up electrical circuits, such as resistors, capacitors, transistors, and diodes. These components are used to control the flow of electricity in a circuit. Electronic components can last anywhere from a few years to several decades depending on the type of component and its usage. Heat, vibration, and humidity can all be factors in decreasing the lifespan of electronic components. Additionally, components can become more prone to failure if not properly tested and replaced periodically.
