Introduction

The W3A45C221KAT2A is an industry proven surface mount capacitor array device, commonly used for transient suppressor applications. It is designed with two capacitors in series on one array device and is typically used for Power Line EMI/RFI noise suppression and DC blocking.

Application Field

The W3A45C221KAT2A capacitor array is suitable for use in a range of applications, such as automotive electronics, consumer electronic devices, computer peripherals and industrial control systems. It is most commonly used in power line EMI/RFI filtering and DC blocking, but can also be used in a variety of other approaches, such as snubber networks, voltage regulators, inverter bridges, switched-mode power supply, multiplexer designs and link-array gate drive amplifiers.

Working Principle

The W3A45C221KAT2A is composed of two capacitors in series mounted onto a single array device. The capacitors are electrically connected to each other, and the series connection enables two nodes in the network. These nodes can be used for power conditioning by filtering off high frequency noise on both the input and output sides.

In power line EMI/RFI filtering, the W3A45C221KAT2A can be used to attenuate any high frequency originating from the power line. This technique is especially effective in strong EMI/RFI noise environments, as the devices can effectively suppress the noise from disturbing the proper operation of sensitive electronic circuits. In order to make sure the device is functioning correctly, it is important to make sure that the impedance of the device is within the specified range for the intended application.

For DC blocking, capacitors can be used in order to block any DC voltage on the output side. The W3A45C221KAT2A can be used for this opportunely, as it can effectively prevent any DC from flowing through the device, allowing only AC signals to pass through. This makes it useful for ensuring that only AC signals reach the connected electronic circuit, while blocking any DC components that would otherwise cause damage to the circuit.

Conclusion

The W3A45C221KAT2A capacitor array is an industry proven surface mount device which is commonly used for transient suppressor applications. It is composed of two capacitors in series, making it suitable for Power Line EMI/RFI noise suppression and DC blocking. In addition, the device can also be used in snubber networks, voltage regulators, inverter bridges, switched-mode power supply, multiplexer designs, and link-array gate drive amplifiers. The device is designed for use in a range of applications, such as automotive electronics, consumer electronic devices, computer peripherals and industrial control systems. It is important to ensure that the impedance of the device is within the specified range for the intended application in order to make sure that it is functioning correctly.
