Capacitor Networks, Arrays and Model W3A45C473MAT2F

Capacitor networks, also known as capacitor arrays, are designed to store and control energy, and they can be used in a variety of applications. One such device is the Model W3A45C473MAT2F, developed by Vishay Intertechnology. This product is a three-terminal capacitor network of 5 fixed capacitors with a zero-ohms resistor between each terminals for additional Power Supply Noise Suppression. It is constructed of 3 DBS ceramic capacitors and 2 DBS tantalum capacitors and is packaged in a white plastic 1206 molded body.

Application field

Model W3A45C473MAT2F is generally used for power supply noise suppression in automotive, telecom, computing and consumer electronic applications. The three-terminal capacitor array is designed to eliminate and reduce the amount of EMI noise that is generated by power supplies connected to the same electrical line or circuit. This EMI noise is caused by spikes and surges in the current or voltage, as well as by the natural harmonics of the board components.

Working Principle

When a capacitor network is connected to an electrical line or circuit, it acts as a low pass filter and stops the transmission of the EMI noise and harmonics. The Model W3A45C473MAT2F is made up of three capacitors and a zero-ohms resistor that are connected in parallel with each other. All of the capacitors are equally charged, and the resistor acts as a bypass for the current and voltage. The three capacitors in the device work in tandem to stop any EMI noise or energy interruptions from entering the line or circuit, providing a better power supply stability and improved efficiency. The device is also designed to dissipate any extra heat made by the connected electrical devices.

Conclusion

Capacitor networks, such as Model W3A45C473MAT2F, are designed to provide power supplies with noise suppression and stability, helping to ensure a more efficient end product. These capacitor networks are used in a variety of applications, from automotive and telecom to computing and consumer electronics. The Model W3A45C473MAT2F is composed of three DBS ceramic and two DBS tantalum capacitors with a zero-ohms resistor, providing a certain level of power supply noise suppression. It is an effective and efficient way to reduce EMI noise and ensure a better, more reliable power supply.
