The Schutzinger MFK 15/1/100/SW is a ferrite core filter that is made for suppressing interference in radio frequency applications. It is encased in a weatherproof, shielded casing for protection against the elements. This filter is made of a ferrite core with 15 ohms of impedance, 1 Amp of current rating, and 100kHz of frequency range. The “SW” denotes that this filter has additional shielding, which helps reduce unwanted noise from entering the system. The MFK 15/5/100/SW can be used in a variety of applications, such as high-speed circuits, automotive audio, wireless data, and more.
