Ferrite cores are formed out of tiny particles of ferromagnetic material, such as iron, nickel, and cobalt. Generally molded into a toroid shape, ferrite cores are used in both structured cabling as well as in interconnecting cables. With its superior magnetic properties and low price, ferrite cores have found wide spread use in various applications.
28B0375-310 is a type of ferrite core, manufactured by Harbortech and available in various sizes. The 28B0375-310 ferrite core is mainly used in structured cabling and interconnecting cables. It has excellent electromagnetic properties and it is also capable of absorbing and dampening electromagnetic fields, making it ideal for applications such as magnetic shielding and interference suppression.
The working principle of the 28B0375-310 is a combination of both inductive and capacitive reactance. At any given frequency, the core provides an inductive reactance, meaning it will resist the passage of direct current, and limit it to a level where the electric field caused by the passing current does not exceed the core’s structural limits. At the same time, the core will also provide capacitive reactance, meaning it will oppose the passage of alternating current. This capacitive reactance is due to the small gap between the core and the cable, which create an impedance to the alternating current, increasing the cable’s inductance.
In short, the 28B0375-310 ferrite core is mainly used as a way to reduce Electromagnetic Interference (EMI) and as a form of magnetic shielding. It works by providing both an inductive and capacitive reactance, and by limiting the amount of direct and alternating current that can pass through the cable. This makes it ideal for applications where EMI is an issue, and where a superior level of electromagnetic shielding is needed.
The 28B0375-310 ferrite core is a cost-effective solution for those looking for solutions to their EMI reduction and shielding needs. The core is durable, has excellent magnetic properties, and is capable of absorbing and damping electromagnetic fields. Thanks to its superior performance and low price, it has become a popular choice among both commercial and residential customers.
