Ferrite Cores, also known as magnetic cores, are used in electrical circuits to provide electromagnetic shielding or to couple signals in various electrical engineering applications. The CV28B1937 is one such example. This ferrite core has a number of features that make it ideal for a wide range of applications.

The CV28B1937 has a 28mm nominal outside diameter, a 17mm nominal inside diameter, and a 37mm nominal height. It has a Nickel-zinc ferrite composition and is specially designed for high frequency applications. It is also a high-gain core that can operate at frequencies of up to 2GHz.

In terms of application fields, the CV28B1937 can be used for the development of high-efficient non-contact type high frequency power supplies, like one in wireless charging and Tesla coils. It is also used in antenna tuners and low-frequency amplifiers. It can be utilized in computer peripherals such as mice and inefficiency Ethernet cables. In addition, it is popularly used in connecting cables, such as HDMI and USB, and in the development of RFID (Radio Frequency Identification) tags.

In terms of working principle, the CV28B1937 has a high permeability which enables it to efficiently channel and store large amounts of magnetic energy. It is designed with an air gap, which helps to reduce losses by capacitive-coupling electromagnetic fields between the cores and shields in the system. This air gap increases conductivity and optimizes coupling between the various components of the system. Thus, the ferrite core can effectively reduce high frequency noise and provide protection from interference.

The CV28B1937 ferrite core is a reliable and efficient component for a variety of electrical applications, from wireless charging to Ethernet cables. Its characteristics make it especially well-suited for applications requiring improved electromagnetic shielding and efficient signal or power coupling. With its high permeability and air gap feature, it is an ideal choice for building high-performance non-contact type power supplies and antenna tuners.
