Ferrite cores are specialized wiring accessories used to adjust the electrical characteristics of cables or transmission lines. Specifically, ferrite cores act as low-pass filters, suppressing electromagnetic interference (EMI) and radio-frequency interference (RFI) signals on the line. The 28R0984-000 is a particularly popular model ferrite core cable, but what does it do and how does it work? This article will explain the application field and working principle of the 28R0984-000.

What Is the 28R0984-000 Ferrite Core?

The 28R0984-000 is a ferrite core cable manufactured by Sumitomo Electric Industries. It consists of a pair of terminals (male and female) and a ferrite core element. The terminals are used to connect the cable to other components in the system, and the ferrite core element is used to shield or filter out unwanted high frequency signals.

The core element of the 28R0984-000 is made of ferrite, a material consisting of iron, nickel and zinc. It is a magnetic material, which provides the necessary field to suppress the high frequency signals. The material also has good electrical insulation properties, which allows the core to act as an effective shield.

Application Field of the 28R0984-000

The 28R0984-000 ferrite core cable can be used in a variety of applications, such as in electrical power transmission lines, in communication equipment, and in medical equipment. It can also be used in automotive applications, such as connecting the Bluetooth module to the vehicle’s electronics. In any of these applications, the ferrite core is used to reduce radiation or suppress high-frequency signals.

Since ferrite cores have a low-resistance impedance and high-frequency suppression, they are also often used in military radio communication and other sensitive applications. In addition, ferrite cores are becoming more important in automotive electronics due to the increased use of infotainment systems, which require high-frequency signals for their operation.

Working Principle of the 28R0984-000

The working principle of the 28R0984-000 ferrite core cable is quite simple. It consists of a pair of terminals connected to a ferrite core element. The core element is made of magnetic material, which generates a magnetic field when an alternating current passes through it. This magnetic field interacts with high-frequency signals, and absorbs and suppresses them.

This suppression effect can be adjusted by changing the amount of current flowing through the core element. The amount of current used can also be adjusted to produce a specific frequency range, allowing the cable to filter out specific frequency bands depending on the application.

Conclusion

The 28R0984-000 ferrite core cable is a special accessory designed to reduce or suppress electromagnetic interference (EMI) and radio-frequency interference (RFI) signals. It is made of ferrite, a material composed of iron, nickel and zinc, which generates a magnetic field when an alternating current passes through it. By controlling the amount of current flowing through the core element, the ferrite core can be used to filter out unwanted high-frequency signals in a variety of applications, such as power transmission lines and communication equipment.
