Ferrite Cores are components often used in cables and wiring, designed to help reduce signal interference. In this article, we will be taking a look at the 28S2011-000, a special type of ferrite core, and its application field and working principles.

Construction

The 28S2011-000 is composed of a mineral ferrite core surrounded by a copper coil. It is designed to fit into TNC terminals, although small variations within the range allow for mounting on circuit boards as well as in SMS reverse threads.

Electrical Properties

The 28S2011-000 has a wire diameter of 0.8mm, and can provide an impedance ranging from 6 ohms to 300 ohms, depending on the application. Its current handling capacity of 20mA in either direction and its capacitance of 0.3pF make it particularly suited for use in high-speed data applications, such as Ethernet cables. The 28S2011-000 also boasts excellent shielding performance, as well as low signal crossing between pin pairs.

Application Field

The 28S2011-000 can be used in a variety of applications, such as Ethernet cables, RF cables, radio receivers and transceivers, and in various power supply lines. It is particularly suited for high-speed communication lines, where increased signal interference is an issue. The 28S2011-000 is also suitable for use in serial cables, such as USB cables, and can help to reduce signal crosstalk and interference in these applications, ensuring reliable data transfer.

Working Principle

The working principle of the 28S2011-000 is simple and easy to understand; the ferrite core of the device functions as a magnetic shield, blocking out unwanted interference from outside sources. The copper coil provides the necessary electrical connections, and helps to transfer the desired signals. The 28S2011-000 operates by absorbing the wave energy generated by the interference and turning it into heat energy.

When an interference signal enters the core, the copper coil responds by inducing a small current, creating an oscillating magnetic field. This field then opposes the incoming signal, causing it to dissipate quickly and without reflecting back to the source. This reduces the amount of interference in the signal, allowing for reliable and error-free communications.

Conclusion

As can be seen, the 28S2011-000 is an effective and reliable solution for applications in which signal interference is a problem. With its excellent electrical properties and shielding performance, the 28S2011-000 can help to ensure reliable and error-free data transmission. Additionally, its easy installation and maintenance make the 28S2011-000 an attractive choice for many applications.
