SB28B0221AT

Ferrite Cores - Cables and Wiring

Ferrite cores are used for various purposes, including providing electrical connection, protecting electrical cables from damage, and acting as an inductance to increase signal strength. One such type of core is the SB28B0221AT. This ferrite core is used in various industrial, commercial, and consumer applications to reduce cable crosstalk, increase signal-to-noise ratio, and improve the overall signal quality.

What is the SB28B0221AT?

The SB28B0221AT is a type of ferrite core manufactured by MuRata Power Solutions. It is a 200 mOhm black nylon 6/6 circular wound ferrite core, which can be used for various purposes, such as a protective sleeve for cables and wires or as an inductor for electronics. The core is 0.875 inch (22.23 mm) in diameter, giving it excellent flexibility. The outer diameter is also 0.14 inch (3.56 mm), which is ideal for fitting into tighter spaces in electrical installations. It also has a 5 kOhm peak inductance value, and can withstand up to 150 VAC.

Application Field and Working Principle

The SB28B0221AT is primarily used in the connection and protection of cables and wires. A typical application would see the core wrapped around a cable to both protect the cable from physical damage as well as to reduce the amount of EMI (electromagnetic interference) present in the signal. The core’s inductance acts as a filter, blocking out any signals that are not in the desired frequency range, thereby reducing the amount of crosstalk. This also increases the overall signal-to-noise ratio, improving the overall signal quality.

The inductance of the SB28B0221AT is also used in electronic applications. By wrapping the ferrite core around a wire, it can act as an inductor, increasing the electromagnetic field created by the current. This field can act as an antenna, allowing for more efficient radio transmission of data. It can also increase the signal strength for any type of frequency-dependent electronic device, such as a clock or motor.

Conclusion

The SB28B0221AT is a useful tool in a variety of electrical and electronic applications. It provides a high level of protection to cables and wires, while also providing inductance for signal enhancement. The core’s small size makes it an excellent choice for tight spaces, while its maximum peak inductance value offers increased signal quality. In short, the SB28B0221AT is an excellent tool for connection and protection of cables and wires, as well as in various electronic applications.
