EMI/RFI (electromagnetic interference/radio frequency interference) filters come in a wide range of shapes and sizes. They are used in a variety of industries and applications, as well as for consumer devices such as computers, TVs, and cell phones. The CM1481-02DE EMI/RFI filter is one such device designed for a specific application. This article will explore the application field and working principle of the CM1481-02DE.

The CM1481-02DE is a surface-mounted EMI/RFI filter. It is designed to offer high levels of immunity to interference. This is achieved through the use of a combination of LC (inductors and capacitors) and RC (resistors and capacitors) networks connected in series and parallel, which act together to reduce electromagnetic interference. The device is rated for a maximum working frequency of 4.2GHz, which is ideal for applications where a wide frequency range is required.

The CM1481-02DE offers excellent protection against EMI/RFI in a variety of applications. It can be used in medical equipment, automotive systems, and aerospace systems, as well as in devices used in consumer electronics. It is also suitable for radio and communications applications, including cell phone towers and satellite ground stations. Additionally, it can be used in military and defense applications, such as in guidance and control systems.

The working principle of the CM1481-02DE EMI/RFI filter is based on the creation of a barrier or shield between the signal source and any unwanted electromagnetic energy. This is achieved through a combination of inductors, capacitors, and resistors connected in series and parallel. The combination of these components creates an effective barrier that prevents the propagation of unwanted noise into the system.

The inductors act as an impedance to the passage of EMI/RFI energy, slowing down the propagation while allowing the desired signals to pass through. The capacitors also block the energy, while allowing the desired signals to pass through with minimal disruption. Finally, the resistors act as a buffer, absorbing any extra energy and preventing it from reaching the signal source.

In summary, the CM1481-02DE is an EMI/RFI filter designed for a variety of applications. It is rated for a maximum frequency of 4.2GHz, and employs LC and RC networks in series and parallel to create an effective barrier between the signal source and any unwanted electromagnetic energy. This filter offers excellent protection against EMI/RFI in a variety of applications, such as medical equipment, automotive systems, and communications systems.
