The beginning of the 21st century is a period of explosion of electronic products. Electronic products such as mobile phones, MP3, MP4, and cameras basically appeared at that time. With the continuous development of the times and the advancement of technology, more and more electronic products Products have entered people's sight, and the appearance of these electronic products has greatly facilitate people’s life and change people’s living style.
Electronic products are composed of different electronic components. Electronic components are divided into active components and passive components. So what are active and passive components? What's the difference between them?
Active components: When electronic components work, there is power inside them. Passive components: When electronic components work, there is no power inside them.
Simply put, a device that requires power to function properly is an active component. A device that does not require a power source to function properly is a passive device.
Common active components include transistors, integrated circuits, and more. Active components are the core of electronic circuits, and all oscillation, amplification, modulation, demodulation, and current conversion are inseparable from active components.
Passive components include capacitors, resistors, etc.. Resistors mainly play the role of limiting current, shunting, stepping down, and dividing voltage in the circuit. Capacitors are indispensable components in the field of electronic power. They are mainly used in power supply filtering, signal filtering, coupling, resonance, and DC blocking in circuits.
Active devices and passive devices have different requirements on the working conditions and working methods of the circuit, but they are all part of the electronic product. Without one of them, the electronic product is incomplete.
Select a reliable manufacturer when purchasing electronic components can avoid a lot of unnecessary trouble. JYH HSU(JEC) Electronics Ltd (or Dongguan Zhixu Electronic Co., Ltd.) is one of largest manufacturers in China in terms of yearly safety capacitor (X2, Y1, Y2) production. Welcome to contact us.
