W3A4YC681MAT2A

Capacitor Networks, Arrays

The W3A4YC681MAT2A is a type of capacitor network or array, the most commonly used of which are array and networked capacitors. In some cases a capacitor network can even be used in lieu of a single larger capacitor. A capacitor network consists of several capacitors often with an equal capacitance (known as an "arrangement") that are connected in parallel or in series and are usually created by soldering them onto a printed circuit board. Networks can use either ceramic capacitors or electrolysi capacitors - the former is generally more common.

Application Field

Capacitor networks or arrays are used in a wide range of applications, most commonly in the audio, automotive and communications industries. They are used to filter and shape signals, create high pass, low pass, and band pass filters, reduce distortion, produce resonance, and create gain or amplification. In audio, they are mainly used to produce equalization effects and control loudness, while in the automotive industry, they are most often used to form part of the antenna system in a vehicle.

Working Principle

The working principle behind a capacitor network or array is based upon the properties of capacitance. When two or more capacitors are connected in parallel, the overall capacitance of the system increases. Similarly, when two or more capacitors are connected in series, the overall capacitance of the system decreases. This capacitance can be used to control the flow of electrical current, thus affecting the shape and magnitude of the signal which is either fed through or generated by the circuit. For example, in audio applications, a capacitor array is often used to shape and control the frequency response of a signal, creating equalization. In automotive applications, antenna networks use the properties of capacitance to form an antenna for receiving or transmitting a signal.
