Introduction of Silicon Capacitors

Silicon capacitors refer to the capacitors made of silicon material. Generally, capacitors are composed of two conductive layers which are separated by dielectric material. In the case of silicon capacitors, silicon layers are used as conductive layers and electric insulation film is used as dielectric material.Silicon capacitors are widely used in various fields such as telecommunication, industrial and domestic devices and consumer electronics. They are mainly used to decouple the power supply and provide stable voltage to the interior of a circuit. Silicon capacitors have high stability and long life, which makes them a preferred choice in many applications.

Properties of Silicon Capacitors

The main characteristic of silicon capacitors is its extremely low series inductance and low current flows through them. This enables them to operate at higher frequencies and are suitable for high speed switching circuits. Moreover, they have high resistance to aging due to their low thermal coefficient of expansion.Silicon capacitors also have low ESR due to their minimal dielectric losses. This makes them preferable for areas such as high frequency switching regulator feedback, switching power supply and class D audio amplifiers. Furthermore, silicon capacitors are available in different configurations, such as radial, axial, surface mount, reflowable, etc.

Types of Silicon Capacitors

Silicon capacitors are classified into two main groups according to their dielectric: Silicon stack capacitors and Rely capacitors.Silicon stack capacitors are composed of multiple layers of silicon and dielectric material, while rely capacitors consists of a single spacer in between the two conductive plates. Silicon stack capacitors are usually used for high frequency applications while rely capacitors are used for applications that require high current capability.

RFCS04023000CBCT1 Application Field and Working Principle

RFCS04023000CBCT1 is a type of rely capacitor which belongs to the Radial Polyester film type rFFE series of rely capacitors. It has an operating temperature of -55 - +125 ℃ and a maximum voltage of 80V AC.RFCS04023000CBCT1 has high ripple current capability, ripple energy, noise absorption, current absorption and energy absorption. Due to this, it is suitable for applications such as power oscillators, switching power supply, power supply filters, DC-DC converters, motor and transformer drivers, relays, electronic ballasts, automotive displays, and high performance audio amplifiers.The capacitor works on the principle of electrostatic field. When a voltage is applied to the two electrodes of the capacitor, a charge is stored in the dielectric material between the two electrodes. This stored charge creates an electrostatic field between the plates. This electrostatic field provides the insulation and allows current to flow through the capacitor when a voltage is applied.
