28B0375-300

The 28B0375-300 is a Broadband Cylindrical Core provides an effective means of reducing common and differential mode EMI. This core is most frequently used to suppress common mode EMI on the internal and external cable assemblies of electronic equipment. By decreasing the levels of EMI radiated by internal cables, ferrite core can reduce the cost and amount of overall shielding required to confines EMI within a product's enclosure. It may also be successfully used on power cables that carry digital or analogue signalling. It is suitable to achieve maximum EMI filtering performance in a given application. The in-circuit impedance may be substantially increased by passing 2 turns of the wire conductor through the ferrite core. A typical common mode application might have two conductors passed through a ferrite core. With equal and opposite currents flowing through the core, zero net bias is established through the component and maximum impedance is thus realized from the ferrite.

• Suitable for applications from 30 MHz ~ 1 GHz
• Available in variety of sizes, custom design also available
