Ferrite cores are used in many electrical applications, and the CF28B1805 is one of the more popular types for modern home networks and consumer electronics. While the core itself consists of nothing more than a ferrite material mixed with powdered iron, it is designed to provide electrical properties that help protect devices from electromagnetic interference (EMI). A ferrite core will promote lower impedance paths for noise coupled onto the transmission lines, which can help reduce both EMI and the amount of leakage current.

The CF28B1805 is a ferrite core designed for cable and wiring applications. It is designed to fit onto the cable or wiring and is typically used to form an inductor for added signal protection. The core features 14C85 mixture and is designed to be used in applications that include high temperature, UL, ULF and RFI/EMI protection. It can be used on a wide variety of cable sizes, including cables from 0.25mm2 to 9mm2 and can be used with cable jackets ranging from 0.2mm to 0.8mm. The core is self-locking and has a relatively low volume so that it can be easily installed, even in tight locations.

The working principle of a ferrite core is largely based on electromagnetic induction. When the current designed to pass through it is still below a certain level, the core will allow the current to flow through with little to no interference. However, when the amount of current present exceeds this threshold, the core will start to actively oppose the current and thus reduce the amount of noise that is travelling down the cable or wiring. This can be used to reduce the levels of interference on a given device and improve performance, while also helping to protect against the damage caused by excessive current.

In addition to protecting circuits and cables from EMI and leakage current, ferrite cores also help reduce the level of ground loop currents that occur when two ground-referenced devices are connected. Ground loop currents can cause a variety of problems, including fluctuations in voltage, interference, and in extreme cases, physical damage to the components of a device. Ferrite cores can block these currents and help ensure that the ground reference of each device remains isolated.

The CF28B1805 ferrite core is designed to be used in a variety of cable and wiring applications. It has a wide range of form factors available and can be used in environments that range from low to high temperatures. Additionally, the core can help to reduce EMI levels, reduce the amount of leakage current present, and protect against the damage caused by ground loop currents. While it may not be the most powerful option available, the CF28B1805 ferrite core is nevertheless a great choice for those looking for a versatile solution that can help protect devices from a variety of different electrical issues.
