Ferrite cores consist of magnetic materials such as iron, nickel, cobalt, and nickel-zinc. They can be used to protect against electrical interference, define electrical flux, and control the flow of magnetic fields. Cables and wiring can be covered with ferrites to reduce noise from emissions, reduce the susceptibility to external noise, and provide a stable operation environment.

The 28B0137-3 ferrite core is a small, lossy iron-based ferrite core that offers excellent EMI noise suppression performance. It is designed to target the high-frequency noise range while minimizing any negative impacts on the desired signal. This makes it ideal for applications such as surround sound or stereo systems where a lot of noise may be generated from the environment.

The 28B0137-3 ferrite core is also suitable for use in consumer electronics and wireless communications. These applications typically rely heavily on frequencies ranging from a few hundred megahertz to several gigahertz, a range that the 28B0137-3 is capable of significantly attenuating. It is also useful for restraining the high-frequency noise of other electric devices that may interfere with each other.

The 28B0137-3 ferrite core works by passing an alternating current (AC) through it. This produces an induced magnetic field which helps to dissipate the AC energy into heat energy rather than allowing it to pass through the core. This effect is known as hysteresis and the dissipated energy is known as a reluctance loss. The ferrite material also helps to temporarily store some of the magnetic energy produced by the AC current, thus providing a form of buffering. This makes it possible to reduce the current in the frequency range of interest.

In order to get the most out of a ferrite core, it is important to match the material’s size, permeability, and form factor to the application requirements. The 28B0137-3 ferrite core is small in size, which makes it well-suited for applications where space is limited. Its permeability is relatively low, meaning that it will not interfere too much with the desired signals. It also has an open-frame structure, which provides an effective way to dissipate any thermal energy created.

The 28B0137-3 ferrite core is a versatile, cost-effective way to reduce noise emissions in a wide variety of applications. It is capable of suppressing a broad range of frequencies, making it suitable for many consumer and industrial applications as well as wireless communication systems. Additionally, its small size makes it well-suited for applications where space is limited. The 28B0137-3 may be used in a variety of supplies, cables, and wiring to minimize interference and create a stable operating environment.
