With the development of science and technology, the rapid development of telecommunications technology, and the growing demand for consumer electronic products, the chip capacitor industry is also advancing rapidly. China has now become a global capacitor manufacturing country. While we are proud of this, let us understand the principle of CBB capacitors. Let's go.
The so-called chip capacitor is a passive device that stores energy in the form of an electric field. It exists in almost all electronic circuits and can play various functions such as DC-DC communication, coupling, bypass, filtering, and tuning. A capacitor is an energy storage component consisting of two metal plates and an insulating dielectric of the interlayer. Any two conductors that are very close together and insulated from each other form a capacitor. When a voltage is applied to the conductor, the capacitor begins to store charge.
The discharge process is the process of releasing the stored charge by the chip capacitor. When the charged capacitor is in a closed path with no power supply, the charge on the negatively charged metal plate will be positively charged under the action of the electric field force. The metal plate runs away, neutralizing the positive and negative charges, and the capacitor begins to discharge.
CBB capacitors have the following advantages: extremely low loss; low dielectric absorption coefficient; high insulation resistance; good frequency characteristics; excellent self-healing properties and high stability.
The CBB capacitor is a capacitor in which a metal foil is used as an electrode, and a polypropylene film is stacked from both ends and then wound into a cylindrical structure. The principle is the same as that of the polyester capacitor, the polarity is low, the insulation resistance is high, and the frequency characteristics are excellent ( The frequency response is wide) and the dielectric loss is small.
CBB capacitors have low loss, strong moisture resistance, excellent electrical performance, good reliability, large capacity, long service life and good self-healing properties. Instead of most polystyrene or mica capacitors, it is used for higher requirements.
