Ferrite cores are used in a variety of electronic devices and components, and 28R0756-000 is one type of ferrite core specifically used in cables and wiring. It is an FCC-approved ferrite core designed for medium frequency range. In this article, we will discuss its application field and working principle.

Application Field

The 28R0756-000 ferrite core is mainly used in cable and wiring products such as computer, communication, instrument, medical equipment, power supply, etc. Specifically, 28R0756-000 is used in:

• Audio and video connectors for devices such as TVs, stereos, and DVD players;
• Computer power supplies and video cards;
• Power supplies and surge protectors for electronic devices;
• Data and communication cables such as ethernet;
• Instrumentation and medical equipment;
• Power lines and power supplies.

It is also used in situations where high frequency interference is an issue, such as computer monitors, cell phones, and Bluetooth devices. Furthermore, 28R0756-000 is used in a variety of consumer electronics applications, including portable CD players, audio systems, and high-speed modems.

Working Principle

The 28R0756-000 ferrite core works by using a magnetic flux to create an electromagnetic field. This process is called inductive coupling, and it works by transferring energy between two objects, such as a cable and a computer, using the principle of electromagnetic induction. When a voltage is applied to the core, it produces a magnetic field. This magnetic field then induces a current in the secondary coil, which in turn produces a voltage and current in the load, thus completing the circuit.

The 28R0756-000 ferrite core also helps to reduce interference by acting as a filter. As the current passes through the core, it interacts with the material in the core and creates eddy currents that reduce the amount of interference. The material in the core also acts as a shield against electromagnetic interference from outside sources.

In addition, the 28R0756-000 ferrite core is designed so that the magnetic field strength is constant, which results in increased efficiency. This means that a current of the same strength will be produced every time the core is used. This makes it ideal for applications where the current needs to be consistent, such as in audio and video products.

Conclusion

The 28R0756-000 ferrite core is an FCC-approved ferrite core designed for the medium frequency range. It is mainly used in cables and wiring products such as computers, communication devices, instrumentation, and medical equipment. It works by using inductive coupling to transfer energy with electromagnetic induction, and it also helps to reduce interference by acting as a filter. The 28R0756-000 ferrite core is an efficient and effective device for a variety of applications.
