With the rapid development of electronic information technology, the update speed of digital electronic products is getting faster and faster. The production and sales of consumer electronic products mainly including flat panel TV (LCD and PDP), notebook computer and digital camera continue to grow, which drives the development of capacitor industry.
So what is a capacitor?
Two conductors close to each other, sandwiched between a layer of non-conductive insulation, this constitutes a capacitor.
Capacitors play an important role in tuning, bypassing, coupling and filtering circuits. It is needed for tuning circuits in transistor radios, as well as for coupling circuits, bypass circuits, etc., in color television sets.
A simple capacitor consists of a plate at both ends and an insulating dielectric in the middle. After electricity, the plate is charged, forming a voltage, but because of the insulation in the middle, so the whole capacitor is not conductive.
In a DC circuit, a capacitor is equivalent to a circuit breaker. Capacitor is one of the most commonly used electronic components, which can store charge.
